4. Purpose ?

5. Quantum Computer
A computer that uses quantum mechanical
phenomena to perform operations on data
through devices such as superposition and
entanglement
Quantum Computer – ½ second
Classical Computer (Binary)
A computer that uses voltages flowing through
circuits and gates, which can be calculated entirely
by classical mechanics
Classical Computer – 100 years

6. Quantum computers are different from
binary, digital electronic computers based
on transistors. Where as common digital
computing requires that the data are
encoded into binary digits (bits), each of
which is always in one of two definite
states (0 or 1), quantum computation uses
quantum bits, which can be in
superposition's of states

9. Qubit
 In a quantum computer, a number of elemental particles such as
electrons or photons
 It can be used (in practice, success has also been achieved with
ions), with either their charge or polarization acting as a
representation of 0 and/or 1.
 It is known as a Qubit

10. HISTORY
1982 - Feynman proposed the idea of creating machines based on the laws
of quantum mechanics instead of the laws of classical physics.
1985 - David Deutsch developed the quantum Turing machine, showing
that quantum circuits are universal.
1994 - Peter Shor came up with a quantum algorithm to factor very large
numbers in polynomial time.
1997 - Lov Grover develops a quantum search algorithm with O(√N)
complexity

11. Currents Developments

12. D-Wave Systems
 D-Wave Systems founded in 1999 one of largest names in
commercial quantum computing systems.

13. D-Wave systems
 128 qubit system costs about $10 million
made by D-Wave Rs . 668650000.00
Indian Rupee
 D-Wave is working with leaders in business,
government and academia on a wide range
of very computationallyintensive
applications that could lead to
breakthroughs
in diverse felds such as systems design and
validation, healthcare, mission planning,
fnancial analysis, global
logistics and defense and intelligence.

14.  Super Computer
 Supercomputers
supercomputer is measured
FLOPS (Floatingpoint
Operations Per Second) or
TEPS (Traversed Edges Per
Second).
 Its uses for many Commerical
uses and many artificial
technology
 Operating systems for
supercomputers include
*BSD, IBM AIX, PUMA O/S,
UNIX, UNICOS, eOS and
other.
 Quantum Computer
 Quantum computer that is
3,600times faster than a
supercomputer at solving
complex problems
 Its uses for
Space,Security,Artifical
Intelligence
 It is Mother of classical
computers
 It is the Algorith Enycrption
systems of extraction
 It can control the Universal
computers.

15. Advantages
 Weapon software
 Defense
 Web
 Computation National Labs
 Financial forecasting systems
 Water Network Optimization
 Radiotherapy Optimization
 Protein Folding
 Machine Learning
 Object Detection
 Labeling news stories and etc

16. Dis-Advantages
 The biggest disadvantage is the fact that it has not been totally
invented yet
 Requires new algorithms to reach its potential
 If a result of a computation happens to not be in a base position,
the answer is too difficult to understand.
 Not a lot of experience.
 Greater need for cooling, example negative 460 degree F
 Its is are very unstable
 A quantum computer could, in theory, be used to calculate
solutions in days, maybe even hours, that would take a normal
computer thousands of years to produce.

17. Future
Not expected to replace traditional computers
any time soon.
Still years away from a universal system.
Potential for advances in artificial intelligence.
