The Theory Of Quantum Mechanics

The Theory Of Quantum Mechanics
Our current inability to find a unified theory for explaining all types of forces in the Universe has
incited us to revise our understanding of the present theories. Out of the four fundamental forces
Nuclear,Electromagnetic,Weak, Gravitational first three are modelled as discrete quantum field
while last one as continuous classical field. As one can 't consistently couple a classical system to
quantum one this leads to the need of quantum mechanical description of the gravity. But there are
still loopholes in our present theories of quantum mechanics so one should aim at their modification
prior to unification. This motivates us to start from the fundamentals and find the limit upto which a
certain approximation of any principle hold.
One of the basic postulates of quantum mechanics is the Born's rule of probabilities. It states that
probability of a particle to lie within a certain volume element, at a particular time and position, is
equal to the square of the wavefunction representing the quantum mechanical state multiplied by the
volume element. This rule is foundational to the theory of quantum mechanics. However, it hasn 't
yet been tested experimentally to appropriate precision although bounds for its validity have been
suggested for triple slit interference experiment. One reason for limiting the accuracy of these tests
can be systematic errors. Another possible source of error can be the wrong application of
superposition principle. In the present work we are

The Real World During Quantum-Mechanical Experiments
We've already discussed some of the experimental phenomena that inspire competing interpretations
or theories of what's going on in the real world during quantum–mechanical experiments. (In brief:
Observing microscopic particles seems to either: cause them to randomly take one result or the
other; create a branching world for every possible outcome; or require hidden variables and allow
for faster–than–light, nonlocal communication. Particles seem not to take one path, not the other, not
both, and not neither, and even act as if they "know" when we're observing them.)
In this final installment of a three–article series, we'll look in very broad strokes at some of the
philosophical implications of these views of quantum mechanics.
I. Logic
Standard logic is two–valued. That just means that each sentence in the logic is true or false, not
both, and not neither. 'My cat's breath smells like cat food' is either true or false; it can't both smell
that way and not smell that way at the same time to the same person, and surely it either does or it
doesn't. But as we've seen, some interpretations of quantum mechanics might suggest adding in a
new value.1 Perhaps Copenhagen–style interpretations indicate that we should have a value of
neither–a truth–value "gap"–and Copenhagen and many–worlds interpretations indicate that we
should have a value of both: a truth–value "glut."2 As it happens, there are independent
philosophical reasons to explore three– or four–valued logics (and

The Subatomic World of Quantum Mechanics
Quantum Mechanics
The Quantum Mechanics are weird, yet incredibly powerful theory of the subatomic world, in which
everyday concepts to do with the forces and motion are seen in a different perspective, as they do
not longer apply in the same way. This calls for a new type of mechanics based on what scientists
call "quantum" rules.
Quantum mechanics are a very complicated matter that scientists don't fully understand yet; they are
in charge of studying the smallest faces of our world. The idea of quantum mechanics was
developed in the 20th century by a German physicist Max Planck who introduced his constant,
called Plank´s Constant (h=6.62606957×10–34 m2 kg/s), which is used to determinate the energy of
a photon. When E=hv (v=frequency). Albert Einstein, Niels Bohr, Paul Dirac and Werner
Heisenberg later extended the theory in the 1920s.
Trying to explain quantum mechanics is like trying to explain how the universe was formed. There
are different doctrines but again, none of them is completely certain.
Although it was a tremendous success to the researchers no one really knows how or why it works.
It makes prediction in the microscopic world that go completely against our common sense. For
example quantum mechanics state that an atom can be in more than 1 place at the same time until
we look at it, since then we force it to make a choice on where he is. Also assures that an atom is
neither a particle nor a wave, it is both and neither at the same time. All these weird

systems such as quantum magnetism, unconventional superconductors, and the quantum Hall effect.

For example, the quantum Hall states, time–reversal symmetric topological insulators, and one–
dimensional topological superconductors, all nicely fit into our classification scheme. Furthermore,
our theory predicts the stability of the edge states of topological insulators/superconductors against
disorder. Our classification scheme has been playing an important role in exploring to new
topological materials. For example, based on our classification, we predicted the presence of novel
three–dimensional time–reversal symmetric topological insulators. This prediction has been
experimentally explored in the B–phase of Helium, and in doped topological insulators.
As illustrated by the above examples of topological phases, an important challenge in quantum
condensed matter physics is: "How do we characterize and study highly quantum and complex
systems?" This question is related not only to topological phases, but to systems at quantum critical
points, systems that can undergo a many–body localization transition in the presence of disorder,
and eigen state thermalization that takes place for closed quantum systems at finite energy density,
etc. In this regard, quantum entanglement has been establishing its status as an important common
language in modern quantum many–body physics, both in condensed matter and high–energy
physics contexts. It has been used to address many fundamental

The Physics Of Quantum Mechanics
Quantum Mechanics is a branch of physics that explains the really small things. These really small
things, such as electrons are studied in an attempt to find out how they behave under certain
conditions. Findings from the studies are then used to explain how the small particles make up and
relate to the bigger parts of the world. Without the discovery of quantum mechanics, the behavior of
small things and how they make up everything would be unknown. Plank sparked the discovered
Quantum mechanics when doing an experiment using heat and light to produce ultra–violet
radiation. What Plank discovered is that light was not constant and could actually be considered
particles. Planks discovery brought about the question of whether small things act like a particle or a
wave. This question was tested in the double slit experiment. It was discovered that electrons act as
a wave and act as a particle. Plank applied his ideas and developed an equation that is used to
describe light as a quanta and not a continuous wave. Plank's equation contained a number today
known as Plank's constant, which is used in many equations involving wavelengths. Quantum
mechanics deals with two principles. The uncertainty principle explains that as an electrons position
is more precise the less accurate speed can be calculated and the more precise speed is known the
less precise the location. The second principle is the correspondence principle and this states that
when the classical theory is

Quantum Mechanics And Its Effect On An Extremely Small Level
Megan Griffin
Quantum Mechanics Quantum mechanics is an account of how things rendition on an extremely
small level. "Protons, Neutrons, and electrons are not balls of matter, but more like little
concentrations of energy. According to the Heisenberg Uncertainty Principle, if we look at or
measure the position of an electron, then other crucial information about it is lost. Also, at the
moment we observe it, it basically gives that electron a position and identity in the realm of the
natural" (Berge). In other words, our observations can alter the experiment and aid the changes as
they explain the results. "Quantum mechanics is just as scientifically provable as Newton physics,
but makes less sense to our intuitive rational minds." (Ford). In science, things we perceive as
particles sometimes act like waves. In return, things we view as waves sometimes act like particles.
For example, when people consider electrons and light, they determine electrons as particles and
light as waves. Although this is accurate, under some circumstances electrons act as a wave or light
acts as a particle. "In an experiment, if you take light and shine it on two slits that are close together,
each slit acts like it admits its own beam of light. If a screen is behind it you will see a pattern of
dark spots and light spots. You can predict this based on the fact that light is a wave. If you take the
light away and do the same thing with a beam of electrons, they do the same thing.

Measurement Based Quantum Computation ( Mbqc )
Quantum entanglement, which is often counterintuitive and was originally questioned by Einstein,
Podolsky, and Rosen (EPR),1 is now recognized as a versatile resource for quantum information
protocols.2,3 In order to meet various requirements for various applications, an important
technological development is to increase the number of available entangled qubits. In particular,
measurement–based quantum computation (MBQC) requires the cluster type of a large–scale
entangled state,4,5 where individual components of the cluster state must be accessible by
measuring devices. The number of entangled qubits with individual accessibility seems to be
currently limited to a moderate scale.6–8 Shifting to the continuous variable (CV) ... Show more

With the time–domain multiplexing, a cluster state of qumodes can be an arbitrarily long chain in
the longitudinal direction by extending the operating time of the cluster–state generator. In spite of
the in–principle unlimitation of the time–domain–multiplexing, the previous experimental
demonstration of a dual–rail CV cluster state was limited in the number of qumodes,13 due to a
technical reason as follows. The optical setup is a large Mach–Zehnder interferometer as depicted in
Fig. 1, including a long optical delay line for a shift of qumodes on a rail. The mathematical
derivation of the cluster state with this setup is contained in Sec. S1 of the supplementary material.
In order to operate this cluster–state generator, the relative phases at all interference points must be
properly locked. For this purpose, modulated bright beams are injected into the optical paths of the
cluster state as phase probes, and their classical interference signals are exploited as error signals for
the feedback control. However, the modulated bright beams are noisy, which obscures objective
quantum–level correlation signals of the cluster state. The noises were circumvented in the previous
demonstration by chopping the bright beams and by detecting the cluster

What Is Quantum Teleportation Real And Achieved Moving An...
Is it possible for an object or a person to be taken apart into atoms and be put back together in
another location, or another word can a person teleport? Even though teleportation sounds like
science fiction, it does indeed exist just in a smaller scale. Up to this day scientists were able to
make quantum teleportation real and achieved moving an atom from location A to location B in
seconds. According to Jon Austin professor Michio Kaku of City University, New York, maintains
the technology to teleport a living person to another part of the Earth or even space could be
available within decades or at by the next century. The existence of an actual teleport has been
proven and demonstrated by Michio Kaku. The overall definition of quantum teleportation is that
something is able to travel from one location to the other instantly and without any contact. The in–
depth definition is that an atom or a molecule can break the distance in a moment without any
contact between location and on a quantum level. Quantum teleportation considers all living and
nonliving things as data. People consist of data that is maintained in atoms and molecules. and
theoretically human body can be taken apart into atoms and put back together in a different place.
Michio Kaku went to high school Kaberle in Palo Alto, California. He was an incredibly gifted
student. As a part of the project at school, he built a particle accelerator in the garage of his parents.
Michio built a machine from 400

Disadvantages Of Quantum Computer

quantum computing based on the theory and calculations provided by the scientists will benefit us in

This is because he proved that due to a classic computers cannot slow down without exponentially,
thus, a classical computers cannot simulate the quantum effects. But a quantum computer can
simulate the physical processes of quantum effects in a real time. They named it as molecular
simulations (Talele etal 2012). This definitely will allow us to study, in remarkable detail, the
interactions between atoms and molecules. This could help medical and engineering field to design
new drugs and new materials (University of Waterloo n.d.). Those pharmacists can know more
about how was the interactions with each other of their products. They also can see the biological
processes after they used a drug on a person to view the interaction of a drug with a person's
metabolism or disease. Meanwhile in the engineering field, they can create new materials such as
superconductors that work at room temperature, nanotechnology, and semiconductor. This has been
theoretically demonstrated to have this incredible potential, but hopefully those benefits would bring

Abstract
Electrochemical behavior and hydrogen evolution reaction of mild steel in sulfuric acid solutions,
containing different concentrations of gamma–Aminobutyric acid (GABA) as a green inhibitor have
been investigated. The electrochemical techniques included Tafel polarization and electrochemical
impedance spectroscopy (EIS). The rate of both the corrosion reaction and the hydrogen evolution
affected significantly by changing GABA concentrations. Polarization results showed that GABA is
a mixed type inhibitor with good inhibition efficiency. Increasing the temperature led to an increase
in the hydrogen evolution rate and a decrease in the total surface resistance value (RT) or the
relative film thickness (1/CT) of the steel. Quantum calculation including EHOMO, ELUMO, the
energy gap (?E) and the fraction of transferred electrons (?N) demonstrated the inhibition ability of
GABA. The results were confirmed by surface examination using scanning electron microscopy.
Adsorption of GABA on the steel surface fitted the Langmuir isotherm. Thermodynamic parameters

Quantum Computing: Breakthrough of the Future Essay
Innovation is the breakthrough to the future. There is a enormous amount of information us humans

SQUID stands for Superconducting Quantum Interference Device. What this device does is, it has a
large metal ring made out of niobium. When niobium is cooled down, it becomes a super conductor
and it starts the quantum mechanical effects. The quantum mechanical effects create states of +1 and
–2 charges from a magnetic spin and the charges rely on what the qubit wants to do. Later on, we
have to make a coupler before the quantum processor has been made. To have a multi–qubit
processor, qubits have to be connected using couplers. How couplers work is, there is a series of
rectangles and there is coupling elements inside those rectangles that allow qubits to transfer and
share information. Now that the coupler is made, the next process is manufacturing the quantum
processor. The processor chips are made, but then they are stamped on silicon wafer. D–Wave, has
created their own series of quantum processors called the Rainer Series and it has 128 qubits which
is wicked fast. A 128 qubit system can calculate how satellites would react to solar wind storms or a
nuclear blast from Earth instantly, which a conventional computer would take weeks. A quantum
computer can get very hot and a quantum chip has to have temperatures below zero to operate
functionally. To achieve this, D–Wave has built a box that is a refrigeration system, it is known as a
dilution refrigerator. Inside the dilution refrigerator, it is cooled to around 20mK and the
refrigerators use liquid Helium as a

Quantum Mechanics : An Integral Part Of Modern Day...
Quantum mechanics are an integral part of modern day technology and contemporary society.
Quantum mechanics are an important part of transistors, the main part of an integrated circuit.
Without the discovery of quantum mechanics, the transistor would not exist. Therefore, computers
and other important modern day technologies would not exist either. Although the idea of quantum
mechanics is a very difficult idea to conceptualize, it is an extremely important concept to grasp in
order to understand many technologies and strange phenomena in the world today. Max Planck, a
physicist from Germany is credited with discovering the concept of quantum mechanics.8 The
theory of quantum mechanics describes the physical properties of atoms, photons, and subatomic
particles at a very small scale. This theory gives a mathematical explanation for the behavior of
particles at the subatomic level. There are three main principles of quantum mechanics. The first
principle of quantum mechanics is quantized properties. Quantized properties are properties of
particles on a very small scale This includes the principle that states that certain properties such as
the location and velocity of objects can only exist in specific amounts. This principle is different
than classical mechanics; classical mechanics states that these properties are continuous, and exist at
more than just a specific set of quantum numbers. Quantized properties explain why there are
emission lines only exist at certain

Entanglement and Quantum Mechanics
Entanglement is one of the most fundamental and yet unintuitive concepts in quantum mechanics.
Maximally entangled two–qubit states, often called Bell states, where shown to violate classical
(local) correlation properties [33, 34] and are an essential building block for quantum
communication and distributed quantum computation. Unfortunately, such entangled states are also
difficult to generate and sustain as interaction with a noisy environment typically leads to rapid loss
of their unique quantum properties. In the context of QSC, such an entanglement has been generated
exploring various types of interactions such as direct qubit–qubit interaction [35, 36], coupling to a
common cavity mode [37] or photon–mediated interactions for qubits embedded in a waveguide
[38].
In this context, remote entanglement of spatially separated quantum systems have important im–
plications in addressing the scaling problem for quantum information processing. Indeed, as a
solution to this scaling issue, we propose here to follow a modular approach where the quantum
information is encoded, protected and locally manipulated in small units consisting of a few cavity
modes or/and few qubits and the communication between modules is ensured through quantum
teleportation techniques. Sharing of a pair of entangled subsystems between two modules is central
for these teleportation pro– tocols. While the isolation of the modules simplifies the scaling by
avoiding any undesired cross–talk between the

The Physics Of Quantum Computers
My topic is quantum computing. We can say that quantum computers are likely to move out of
science fiction and research labs and into practical applications. A quantum computing is way faster
than a normal pc. Google already have one and make many test online. A quantum computer is a
new complex technology. This computer is not available for us yet. This new engine represent a lot
of new possibility for us. Some person tell that the teleportation would be available, but this is too
far. Old computers can't afford all what a quantum computer can do, and that mean one day they will
disappear. Quantum computing has a lot of benefice, for example, it uses superposition, help to
improve the actual technic by solving problems that are too complex for today's computational
systems, and are have a lot of requirement to work properly.
Quantum computer are fascinating. Even better, a quantum computer is a computer design which
uses the principles of quantum physics to increase the computational power. A traditional computer
can't reach the same level of power or operations. A quantum physics is the study of matter and
energy at the molecular, atomic, nuclear, and even smaller microscopic level. Also, thanks to
superposition and entanglement, a quantum computer can process a vast number of calculations
simultaneously. Where a classical computer works with ones and zeros. "Superposition is essentially
the ability of a quantum system to be in multiple states at the same time" (IQC,

Applying Two Kinds Of A Spherically Symmetric...
In this work, we consider two kinds of a spherically symmetric semiconductor quantum dots: (a)
type I single quantum dot (SQD) with radius r_1, in which electrons and holes are confined in the
same region of space, and (b) type II core/shell quantum dot (CCQD) with the same core radius, r_1,
coated with shell thickness t=r_2–r_1, in which the spatial confinement of electrons and holes
depends strongly on the geometrical parameters (core radius and shell thickness) and strain effects.
Due to the potential structure of CdSe/CdTe CCQD, electrons mainly reside in the CdSe core
region, while the holes dwell mainly in the CdTe shell region. This separation is shown in Fig. 1.
For clarity, we designate the band–gap energy, the conduction band minimum (CBM) and the
valence band maximum (VBM) of bulk semiconductor materials in the unstrained case by E_g0î,
E_c0î and E_v0î, respectively. E_cî and E_vî denote the bulk band edges of each
nanoheterostructure compound including strain effect. In this paper, the index i=1,2,3 refers to the
CdSe region (1), CdTe region (2) and the external medium (3), c(v) holds for conduction (valence)
band and e(h) holds for electron (hole). E_g and V_(e(h)) are the bulk gap energy and the electron
(hole) confining potential of strained hetero–nanocrystal, respectively. In Fig 1, ε_1, ε_2 and ε_3 are
dielectric constants of core, shell and external medium, respectively. For simplicity, we assume that
the potential outside each kind of nanocrystal is

change, collaborate with subordinates in the identification and realization of both goals and
opportunities, and empower those around them to be effective and productive. It is traits such as
these that are particularly vital during times of upheaval, transition, and change. The theory places

not a single theory is acceptable by the whole scientific community to postulate the phenomena. The

The inadequacy and weaknesses of modern science is thus manifested as a result of its ignorance on
other sources of scientific knowledge such as metaphysical and spiritual knowledge which is proven

particular sciences and acts as a source of conceptual framework for the unity of science and
spiritual knowledge. There are a number of cosmological principles in Islamic science which are
formulated based on the relevant Qur'anic verses, prophetic traditions and intuitive knowledge of
famous traditional Muslim scholars. In this study, the principles and ideas of quantum mechanics are
presented in a simplified manner for easy understanding of the subject matter, followed by the
application of the principles in Islamic science wherein the relevant issues are discussed

A Brief History of Quantum Mechanics
Quantum theory began to take shape in the early 20th century, when classical ideas failed to explain
some observations. Previous theories allowed atoms to vibrate at any frequency, leading to incorrect
predictions that they could radiate infinite amounts of energy; a problem known as the ultraviolet
catastrophe. Max Planck in 1900 solved this problem by assuming the vibrations of atoms at specific

Quantum Chromodynamics : The Theory Of The Strong Reaction...
The theory of the strong interaction force –– Quantum Chromodynamics (QCD) –– predicts that at
sufficient high temperature and/or baryon density, nuclear matter undergoes a phase transition from
hadrons to a new state of the deconfined quarks and gluons: the quark gluon plasma
(QGP)~cite{Bjorken:1982qr}. Over the past two decades, ultra–relativistic heavy–ion collision
experiments at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC)
have been searching and exploring this new state of matter under extreme conditions. Compelling
discoveries, for instance the strong suppression of hadrons at large transverse momenta (jet
quenching), reveal the creation of the QGP medium at RHIC and the LHC~cite{Teaney:2000cw}.

In current studies of the open heavy flavor diffusion coefficient, it is common that the diffusion
coefficient is directly or indirectly encoded in the model and one can relate its physical properties to
one or multiple parameters. By comparing the heavy quark observables (such as the nuclear
modification factor $R_{mathrm{AA}}$ and elliptic flow $v_2$) between the theoretical
calculation and the experimental data, these parameters can be tuned until one finds a satisfactory
fit. However, the disadvantage of such an "eyeball" comparison is that it gets exceedingly difficult to
vary multiple parameters simultaneously or to compare with a larger selection of experimental
measurements, as all parameters are interdependent and affect multiple observables at once.
%~cite{Andronic:2015wma}.
A more rigorous and complete approach to optimizing the model and determining the parameters
would be to perform a random walk in the parameter space and calibrate to the experimental data by
applying a modern Bayesian statistical analysis~cite{Higdon:2014tva,Higdon:2008cmc}. In such
an analysis, the computationally expensive physics model is first evaluated for a small number of
points in parameter space. These calculations are used to train

Experimental Confirmation : Physics Of Quantum Mechanics
2.4.1 Experimental confirmation
Matter waves were first tentatively affirmed to happen in the Davisson–Germer test for electrons,
and the de Broglie theory has been affirmed for other rudimentary particles. Moreover, nonpartisan
particles and even atoms have been indicated to be wave–like.
(A) Electrons
In 1927 at Bell Labs,Clinton Davisson and Lester
Germer let go moderate moving electrons at a crystalline nickel target.
The precise reliance of the reflected electron force was measured, and was resolved to have the
same diffraction design as those anticipated by Bragg for x–beams. Prior to the acknowledgement of
the de Broglie speculation, diffraction was a property that was thought to be just shown by waves.
Subsequently, the vicinity of any diffraction impacts by matter exhibited the wave–like nature of
matter. At the point when the de Broglie wavelength was embedded into the Bragg condition, the
watched diffraction example was anticipated, in this way tentatively affirming the de Broglie
speculation for electrons.
This was an essential bring about the advancement of quantum mechanics. Exactly as the
photoelectric impact showed the molecule nature of light, the Davisson– Germer examination
demonstrated the wave–nature of matter, and finished the hypothesis of wave–molecule duality. For
physicists this thought was paramount in light of the fact that it implies that can any molecule
display wave attributes, as well as that one can utilize wave mathematical

Goal: Synthesize Cadmium Selenide (CdSe) Quantum Dot Crystals using Cadmium Oxide (CdO)
and Selenium (Se) dissolved in Triphenylphosphine solution. The product created will be a colloidal
solution, bound to the exterior of the crystal lattice and it remains soluble in the octadecene
(Boatman & Nordell). Along with this the product will most likely vary in color as well due to the
changes in wavelength, energy and transitions, that all correspond to a smaller crystal. The
variations in particle size will prove to be an important feature in the experiment, so the goal is to

since they do not settle.
Background of the Chemistry: Cadmium Selenide is an inorganic compound that is widely used for
research on nanoparticles. Cadmium Oxide is an inorganic compound that is mostly used for
creating other cadmium compounds because it crystallizes in a lattice like that of NaCl. Selenium is
an element that has nonmetal properties, but it is rarely ever found in its pure state, it is often found
as a compound. Both, selenium and cadmium are used to synthesize the CdSe used in this
experiment. Although these materials can be very hazardous, it has been proven that using these
items are the best option for this synthesis. The reasoning for this includes the temperature needed to
grow them and they have higher

A Short Story on the Life on Quantum Physicist Kennen Hertz
Locked away in the basement of a Stanford lab, aspiring quantum physicist Kennen Hertz was
staring at the same immense board of mathematical equations that he had been staring at for the last
three months. "If I could only find some pattern in these measurements, it's all that's in the way
between me and my Ph.d! Everything is put together reasonably, so how come I can't find the reason
in this?" He was so lost in thought sitting there brooding over the apparent lack of logic in sub–
atomic particles, that he barely noticed his undergraduate assistant walk in. "Still no luck?" she
asked, "Luck doesn't solve quantum mechanical theories." he retorted.
While he usually liked Emma, she had an annoying habit of being rather...what was the right word?
Fanciful, yes that was it. Still she was an excellent assistant, kept perfect record data records, was
always on time, and perpetually cheerful. "I think I'll quadruple check that the data is charted
correctly" he decided, "Emma did you take my pencil that was here on the desk?" As he quickly
checked all around the aforementioned desk, she chuckled and handed him a different pencil saying,
"The lab fairies must have stolen another one of your pencils, what is that, the sixth one this week?"
"This is a lab studying one of the most complex forms of science known to humans right now, you
of all people should know that there's a logical explanation as to where all the pencils are going!"

A Brief Look at Quantum Optics
Quantum optics tells us that left (l)– and right (r)–circularly polarized (CP) photon conveys
"integer" spin angular momentum, +ℏ and –ℏ, respectively, although photon is massless elemental
particle. The nature of "integer" spin obeying Bose–Einstein statics makes plural spins confine in an
ultrasmall temporalspace with the same quantum state, meanwhile, "half integer" spin like electron
denies to share the same quantum state in a molecular space, well–known as Pauli exclusion
principle. Intense CP–photon acts as an energy source that preferentially generate optically active
substance from prochiral substances and/or to preferentially decompose one enantiomer from
racemic mixtures. On the other hand, weak CP–photon is used as a probe to detect substance
chirality in the ground and photoexcited states, known as circular dichroism (CD), optical rotation
dispersion (ORD) and circularly polarized luminescence (CPL) spectroscopy.1 Knowledge and
understanding an efficient generation and reversibility of optically active substances from achiral
precursors in the absence of chiral chemical influence has long been a challenging subject among
chemists and scientists. This approach called absolute asymmetric synthesis (AAS) is beneficial to
avoid multiple–step synthesis that often require designed catalysts and specific chiral chemical
sources with high ee.2 So far, several AASs have been employed, including spontaneous symmetry
breaking crystallization, vortex stirring,3f–3h

Quantum Neural Network
1.1 Introduction and Background
The eld of arti cial neural networks (ANNs) draws its inspiration from the working of human
brain and the way brain processes information. An ANN is a directed graph with highly
interconnected nodes called neurons.Each edge of the graph has a weight associated with it to model
the synaptic eciency. The training process involves updating the weights of the network in such a
way that the network learns to solve the problem.
The neurons in the network work together to solve speci c problems.
The network can be trained to do various tasks like pattern recognition, data classi cation,function

The parallel universe interpretation or the many world interpretation of quantum mechanics was

It says that there exists an in nite number of coexisting universes and each possible outcome of an
event occurs in a parallel universe. According to the theory superposition states of a wavefunction
lies in di erent universes and the quantum system interacts with itself in di erent universes. Any
act of measurement sees the state only in one universe.
This interpretation can help in better understanding of the eld of quan– tum information.

Causality, Hume, and Quantum Mechanics Essay
Causality, Hume, and Quantum Mechanics
It is my intention, in the course of this essay, to take the work of David Hume and reapply it to
causality using quantum mechanical theory.
When I refer to causality, I am referring to the belief that events have a relationship of action A
causing action B where A is considered to be the final cause of B. I also refer to the belief that
we can know and understand these causal relationships and thusly know how the system works.
This is a concept that I do not agree with. This mechanistic causality, I feel, is a category of the
mind.
I wish to make it clear, before I begin, that I am not questioning the idea that cause/effect
interactions do occur in reality. I am, however, ... Show more content on Helpwriting.net ...
Instead of saying, I dropped the egg, it broke because of that action, one would say or think, The
event of the egg breaking is an event preceded by an acceleration downward toward the floor. That
event is preceded by a slip of my hand, or some external force. The event of the slip is preceded by a
distracting thought and/or a moistening of my hand from contact with a wet surface, or by neither
event. The event of the distracting thought being preceded by a memory of meeting an attractive
person and/or having too much coffee, or by neither event. The event of the moist hand being
preceded by failing to wipe the counter properly and/or inadequate drying of my hands, or by
neither event. To be thorough, each of these strings of events would have to be traced back through
each branch and go back until one finally reaches the beginning of each string of events, the
beginning of the universe, if there is one.
But even this examination of events is not sufficient to describe all that goes on in this event. Each
portion of the causal mechanism is divisible within itself into internal causes.
Take the slip of the hand as an example. Some internal firing of neurons resulted in the slip of the
hand. To be thorough, we

Taking a Look at Quantum Cryptography
Quantum Cryptography is the newest technology in the field of Encryption and proved to be most
secure as of now. In this paper we will discuss what quantum cryptography is and what makes it
most secure and unbreakable.
Introduction
All our classical computer cryptography methods are basically based on some mathematical
calculations which are quiet easy to implement in one direction but very difficult to process in the
other direction. As RSA(Rivest–Shamir–Adleman) algorithm which is one of the first practicable
and most famous public–key cryptosystems, RSA, is based on the technique of factoring large
numbers which makes it secure. Difficulty in factoring increases with number of digits in RSA key.
For example, a 128 digit number would take millions of years to factor with current computers.
There are still limitations in classical cryptography, it is purely mathematical and information cannot
be separated from its physical representation. In Classical physics, we use binary form to store and
process the data. In the 1980s, C.Bennet, P.Benioff, R.Feynman and others observed that new and
very powerful ways of information processing are possible with quantum mechanical systems. This
gave birth to the concept of quantum computing.
We have algorithms such as Shor's Algorithm, a quantum computer can break a very large number
into its prime factors otherwise which could take millions of years to be solved. The day when
quantum cryptography will become a reality, above

Quantum Physics : Quantum Computing
Quantum Computing
Less than 100 years ago, beginnings of the new quantum theory began. Only about 55 years after
the new quantum theory began to emerge the idea that quantum phenomena can be used to perform
computations. The idea being for a quantum computer was that classical computers would take an
extremely long time to perform huge calculations, when a simple quantum system perform these
same calculations all the time.
One property that quantum computers have been observed to have was the ability to solve
exponential growth problems without using the exponential growth in the time taken to complete the
computation. This observation represents a characteristic named quantum parallelism. When an
input is submitted in a classical computer the same outcome will always be computed. For a
quantum computer there will be many different outputs from just one single input submission. This
is because the quantum computer will compute all possible outcomes for that input simultaneously.
A quantum computer is similar to a computer, but uses the principles of quantum physics to increase
the power of the system beyond what a traditional computer can compute. A traditional computer
functions by storing data in a binary format, using bits that encode with either a 0 or a 1. On the
other hand, a quantum computer will use quantum bits that will encode both the 0 and the 1. The
main difference is the 0 and 1 will encode into two distinguishable quantum states. The quantum

Research Paper On Quantum Entanglement
Quantum Entanglement Quantum entanglement, also known as spooky action at a distance as first
referred to by Einstein, is a phenomenon which occurs when two or more particles interact in such a
way that their physical states can be described as one whole system rather than as each particle
separately. The particles spin in opposite directions to each other and, no matter how far away each
particle is from the other, if one particle changes its spin the other particle/s will instantaneously
change their spin too in the exact opposite direction. You can, therefore, determine the physical state
of each particle just by examining the state of one particle. History: In 1935, Albert Einstein, in a
joint paper with Boris Podolsky and Nathan Rosen, ... Show more content on Helpwriting.net ...
Thus each particle would contain the necessary information with it resulting in there being no need
for information to be transmitted between the particles when they are measured. This theory was
originally seen by Einstein and by many others as the only explanation to the paradox and they thus
accepted that the quantum mechanical description must be

An Adventure of the Quantum Universe in Alice in...
The novel, Alice and Quantum Land, by Robert Gilmore is an adventure in the Quantum universe.
Alice, a normal teenage girl, goes through quantum land and understands what quantum is and how
it works. The quantum world is a difficult one to understand, as its nature is one of complex states of
being, natures, principles, notions, and the like. When these principles or concepts are compared
with the macro world, one can find great similarities and even greater dissimilarities between the
world wherein electrons rule, and the world wherein human beings live. In Alice in Quantumland,

anthropomorphic creatures into the minute world of quantum mechanics, and ... Show more content

All in all, this idea is one of the more significant ideas in the book.
Moreover, the principle of superposition states that if the world can be in any configuration, any
possible arrangement of particles or fields, and if the world could also be in another configuration,
then the world can also be in a state which is a superposition of the two, where the amount of each
configuration that is in the superposition is specified by a complex number. Superposition is a
principle of quantum theory that describes a challenging concept about the nature and behavior of
matter and forces at the sub–atomic level. The principle of superposition claims that while we do not
know what the state of any object is, it is actually in all possible states simultaneously, as long as we
don't look to check. It is the measurement itself that causes the object to be limited to a single
possibility. In the novel, the mechanic mentions to Alice the Schrodinger experiment. This
experiment was analogous to superposition in the macro world. Schrodinger's experiment was to put
a cat, flask of poisonous glass, and a mechanism to break the flask should substance decay in a
closed box. Mechanic then stated that the substance may or may not decay, therefore, according to
the rules of quantum physics you would have a superposition of states, in some of which the decay
would have happened and in others it would not. Of course,

Architectures for Scalable Quantum Computation Essay
1. Introduction
A classical computer represents an implementation of a (sub–) Turing machine that is limited by the
laws of classical physics. As such, certain computational problems are either extremely difficult to
solve or are intractable (w.r.t. resources). In order to tackle these problems, a super–Turing
computational model has been devised and named as the quantum computer [1]. Quantum
computation is based on the laws of quantum mechanics and can outperform classical computation
in terms of complexity. The power comes from quantum parallelism that is achieved through
quantum superposition [2] and entanglement [3]. Computability is unchanged so intractable
problems are still unsolvable, but the exponential increase in speed means ... Show more content on

This requires use of large amounts of auxiliary qubits (aka. ancillae). Further fault–tolerance is
achieved by applying the error correction codes recursively (in levels) [9], exponentially increasing
overhead and reducing fault probability. Due to these error correction schemes, a single logical qubit
is represented by multiple physical qubits. As an example, a single logical qubit at two levels of
recursion is represented by 49 [10] or 81 [11] physical qubits, depending on the error correction
code used. Intuitively, the number of physical qubits required for interesting integer factorisation
described in [4] would be in the thousands. This is a problem because most investments into
manufacturing technology went into silicon–based devices and technology such as ion–traps [12,13]
are not as well developed. Hence, initial proposals for quantum architectures such as the Quantum
Logic Array (QLA) [14] are space inefficient and somewhat impractical. This review attempts to
give an outline of the current state of quantum computing architectures based on the QLA and
provide critical comments.

architectural designs of a trapped ion quantum computer based on the quantum charge coupled

Quantum Mechanics Essay
Quantum Mechanics
Quantum Mechanics is the science of subatomic particles and their behavior patterns that are
observed in nature. As the foundation of scientific knowledge approached the start of the twentieth
century, problems began to arise over the fact that classic physical ideas were not capable of
explaining the observed behavior of subatomic particles. In 1913, the Danish physicist Neils Bohr,
proposed a successful quantum model of the atom that began the process of a more defined
understanding of its subatomic particles. It was accepted in the early part of the twentieth century
that light traveled as both waves and particles. The reason light appears to act as a wave and particle
is because we are noticing the ... Show more content on Helpwriting.net ...
This observance is what Werner Heisenberg refereed to as the principle of uncertainty, which
commonly became known as Heisenberg's Uncertainty Principle. We have the illusion that position
and momentum can co–exist in large objects whose inherent action is huge compared to subatomic
particles. Heisenberg realized that the uncertainty relations had profound implications. Heisenberg
set himself to the task of finding the new quantum mechanics to explain what his theories observed.
He relied on what can be observed, namely the light emitted and absorbed by the atoms. By July
1925, Heisenberg wrote his answer in a paper. The basic idea of Heisenberg's paper was to get rid of
the orbits in atoms and to arrive at new mechanical equations. Heisenberg's approached focused
mainly on the particle nature of electrons. The mathematics Heisenberg used were tables commonly
used for multiplication of arrays of numbers–mathematical objects known as matrices. Using the
mathematics of matrices, scientists had at last a new mechanics for calculating the quantum
behavior of particles. Heisenberg, and others showed that the new quantum mechanics could
account for many of the properties of atoms and atomic events.
Most physicists were slow to accept matrix mechanics because of its abstract nature. Erwin
Schrodinger came up with a mathematical equation which nicely described the wave nature of
electrons. Scientists gladly

Taking a Look at Quantum Dots
To begin with in layman's language or maybe for a person who has limited or little knowledge about
physics, quantum dots are materials that are small but are sufficient to exhibit quantum mechanical
properties. Quantum dots were first discovered in 1980. They exhibit electronic properties which are
between semiconductors and discrete molecules. That is the very reason for the unusually high
surface to volume ratio. The most visible use of quantum dots is in fluorescence where the
nanocrystal is capable of producing different distinctive colors determined by their particle size.
For the more experienced and the more technical personals, Quantum dots are semiconductor
nanostructures confining the motion of the conduction band electrons, the valence band holes or the
excitons and are in all the three spatial directions. The excitons are confined to the three spatial
directions only. There would be a doubt about what excitons is thus the definition; an exciton is a
state or rather a bound state of an electron or a hole which are attracted to each other by the
coulombs force. They are neutral quasiparticles that are generally existent in semiconductors and
also in insulators. They may also be found in some liquids.
The reasons for confinement can be electrostatic potential which can be due to external electrodes,
strain, impurities and doping. According to a lot of research that has been going on in this field, a
quantum dot has a discrete quantized energy spectrum.

Quantum Teleportation And Its Effect On Human Life
Since 1993, when the concept was first introduced by Bennett et al., numerous attempt have been
made to practically implement Quantum teleportation. Quantum teleportation was first demonstrated
with entangled photons[11] in 1997. Later, various developments have been achieved in laboratory,
including the demonstration of entanglement swapping[12], open destination teleportation[13] and
teleportation of two bit composite system[14]. Entanglement distribution has been shown with fiber
links[15–18]. In addition, practical quantum teleportation have been realized via fiber links[19,
20] and limited to a distance of about one kilometer. Experiments have achieved free space
distribution of entangled photon pairs over distances of 600 m[21] and 13 km[22]. Later, entangled
photons were transmitted over 144 km[23, 24]. In these experiments, either only one photon was
transmitted[23] or the entangled photon pair was transferred together[24] using only a one–link
channel. Most recently, following a modified scheme[25], quantum teleportation over a 16 km free–
space links was demonstrated[26] with a single pair of entangled photons. However in this
experiment, the unknown quantum state must be prepared on one of the resource entangled qubits
and therefore cannot be presented independently.
Quantum cryptography, specifically Quantum key distribution is one important field where quantum
teleportation can be practically applied to provide completely secure information exchange between

These individuals cite a three qubit impasse, which states that because quantum computers have
not become more complex than three qubits, they will not become more complex than three qubits.
From the start of serious research in 2001 up until recently, this argument had remained tenable. But,
the human endeavor to create technological advancements would not relent. This drive proved itself
as successful in 2012, when D–Wave Systems, a quantum computing company founded in 1999,
announced that their work on a 512 qubit quantum computer had concluded. D–Wave then went on
to state that they would computer would reveal the computer later that year, albeit with a limited
range of abilities. Since then, companies such as Google and the National Aeronautics and Space
Association (NASA) have begun to work in conjunction with D–Wave to improve upon their
prototype and apply them to calculations to discover new potential. Nevertheless, dogmatic
advocates for RSA hold the proposition that their point still stands as these do not count as full–
fledged quantum computers. With the progression of time, the development of quantum computers
will do as it has already done once and relegate the power of the three qubit impasse to a continually
smaller role.

In our computers, circuit boards are designed so that a 1 or a 0 is represented by differing amounts
of electricity, the outcome of one possibility has no effect on the other. However, a problem arises
when quantum theories are introduced, the outcomes come from a single piece of hardware existing
in two separate realities and these realties overlap one another affecting both outcomes at once.
These problems can become one of the greatest strengths of the new computer however, if it is
possible to program the outcomes in such a way so that undesirable effects cancel themselves out
while the positive ones reinforce each other. This quantum system must be able to program the
equation into it, verify its computation, and extract the results.
Several possible systems have been looked at by researchers, one of which involves using electrons,
atoms, or ions trapped inside of magnetic fields, intersecting lasers would then be used to excite the
confined particles to the right wavelength and a second time to restore the particles to their ground
state. A sequence of pulses could be used to array the particles into a pattern usable in our system of
equations. Another possibility by Seth Lloyd of MIT proposed using organic–metallic polymers
(one–dimensional molecules made of repeating atoms). The energy states of a given atom would be
determined by its interaction with neighboring atoms in the chain. Laser pulses

The Controversy In Quantum Physics Circles
Quantum physics is mind–bending, counterintuitive, and close to impossible to understand. It's so
complicated that a theory saying our reality is just one of an infinite web of infinite timelines is one
that's actually simpler than what most quantum physicists believe. That neat–and–tidy explanation is
known as the many–worlds interpretation, and it has caused plenty of controversy in physics circles.
In the 1950s, a student at Princeton University named Hugh Everett III was studying quantum
mechanics. He learned about the Copenhagen interpretation, which says that at the very, very
smallest level–what we mean when we say quantum–matter exists not just as a particle and not just
as a wave, but in all possible states at once (all of those states ... Show more content on

According to Everett's theory, in this timeline, the object is a particle, but there's another timeline
where it's a wave. Even more baffling, this implies that quantum phenomena aren't the only things
that split the universe into separate timelines. For everything that happens, every action you take or
decide not to take, there are infinite other timelines–worlds, if we may–where something else took
place. That's the many–worlds interpretation of quantum physics. It may not seem like it, but it's
actually simpler than the Copenhagen interpretation–it doesn't strike an arbitrary line between the
quantum world and everything else, because everything behaves in the same way. It also removes
randomness from the picture, which helps the math work out nicely.
Not all physicists subscribe to this theory–a recent poll found that the majority are Copenhagen all
the way–but a growing minority do. Sean Carroll, for one. He explains that many objections to the
theory arise because people come at it from a classical physics point of view. In classical
mechanics...it's quite a bit of work to accommodate extra universes, and you better have a good
reason to justify putting in that work, he writes. That is not what happens in quantum mechanics.
The capacity for describing multiple universes is automatically there. We don't have to add

The Physics Of Quantum Mechanics
Quantum mechanics was developed over many decades ago,Quantum mechanics is science dealing
with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and
account for the properties of molecules and atoms and their constituents–electrons, protons,
neutrons, and other more particles. This type of physics beginning as a set of controversial
mathematical explanations of experiments that the math of classical mechanics could not explain. It
began at the turn of the 20th century, around the same time that Albert Einstein published his theory
of relativity, a separate mathematical revolution in physics that describes the motion of things at
high speeds. Unlike relativity, however, the origins of quantum mechanics cannot be attributed to
any one scientist. Rather, multiple scientists contributed to a foundation of three revolutionary
principles that gradually gained acceptance and experimental verification between 1900 and 1930.
One experiment that is known in this field of physics is the double slit experiment. The double–slit
experiment is a demonstration that light and matter can display characteristics of both regular
defined waves and particles; in addition, it displays the fundamentally probabilistic nature of
quantum mechanical occurrence. A simpler form of the double–slit experiment was performed
originally by Thomas Young in 1801. He believed it demonstrated that the wave theory of light was
correct and his experiment is
