Quantum teleportation involves entangling two particles so their states are dependent on each other, allowing one to be affected by measuring the other. It could allow transmitting quantum information without physically transporting particles. While theoretically possible, scientists are skeptical it can be done for large objects like humans, as the required precision to reconstruct an exact replica is extremely high. Potential applications include quantum cryptography and quantum computing.

3. INTRODCTION:
 Ever since the wheel was invented more than 5,000 years
ago, people have been inventing new ways to travel faster
from one point to another. Such as chariot, bicycle,
automobile, airplane and rocket etc…have all been invented
to decrease the amount of time we spend getting to our
desired destinations.
 Yet each of these forms of transportation shares the same
flaw. They require us to cross a physical distance in which can
take anywhere, from minutes to many hours depending on the
starting and ending points.
 Some scientists working right now on such a method of travel,
combining properties of telecommunications and
transportation to achieve a system called teleportation.

4. What Teleportation is..??
Teleportation:
Teleportation is a process in which scans the objects
dematerialized and transmitted to another location with
the object rematerialized back to original state.
has Teleportation system is unique and has been designed to
allows communicate naturally with anyone or any group of
people anywhere in the world to
Teleportation is the name given by the science fiction
writers to the feat of making an object or person
disintegrate in one place while the exact replica appears
somewhere else.

Need for Teleportation

6. In 1993, the idea of teleportation moved out of the realm of
science fiction and into the world of theoretical possibility.
The idea was first expounded by Charles Bennett and his
co-workers from IBM. They confirmed that quantum
teleportation was possible, but only if the original object
being teleported was destroyed.
The procedure for teleportation in science fiction
varies from story to story but generally goes as follows:
 A device scans the original object to extract all the
information needed to describe it.
 A transmitter sends the information to the receiving
station to obtain an exact replica of the original.
IDEA OF TELEPORTATION:

7.  Basically there are two types of Teleportation
 Classical Teleportation
 Quantum Teleportation
 In Classical teleportation the exact replica of the
source object is obtained at the destination.
 Whereas in Quantum teleportation the exact copy of
the source object is obtained at the destination and
the source object is destroyed.
CLASSIFICATION OF TELEPORTATION:

8. QUANTUM TELEPORTATION:
 Quantum teleportation is a process by which quantum
information (e.g. the exact state of an atom or photon) can be
transmitted. Quantum teleportation is the making of an object
or person disintegrate at one place while a perfect replica
appears somewhere else.
Quantum teleportation involves entangling two things, like
photons or ions, so their states are dependent on one another
and each can be affected by the measurement of the other's
state.

9. 1.Scanning the object completely at
the source side.
2.Dissembling the scanned data
and sending it to the destination.
3.Assembling the object from the
data which was sent to
the destination.
STEPS INVOLVED

10. This principle states that you cannot simultaneously
measure the position and the velocity of a quantum
particle.
Measurement of one value changes the other value
accordingly.
 The law makes it impossible to measure the exact
quantum state of any object with certainty.
In order to teleport a photon without violating the
Heisenberg Principle, a phenomenon is used known as
“Entanglement”.
Heisenberg’s Uncertainty Principle:

11. QUANTUM ENTANGLEMENT:
The existence of an “entangled state” was suggested in an
experiment by the 3 scientists
It states that when two particles come into contact with one
another, they can become “entangled".
In an entangled state, both particles remain part of the same
quantum system so that whatever you do to one of them
affects the other one in a predictable way. Thus, it shows
how, in principle, entangled particles might serve as
"transporters" of sort.

12. HUMAN TELEPORTATION:
We humans are made up of approximately atoms /photons 1028
 For a person to be transported, a machine would have to be built that
can pinpoint and analyze all of the 1028 atoms that make up the human
body.
That's more than a trillion atoms. This machine would then have to send
this information to another location, where the person's body would be
reconstructed with exact precision.
Molecules couldn't be even a
millimeter out of place,
lest the person arrive with some severe
neurological or physiological defect.

14. ADVANTAGES:
Substantial savings in travel and accommodation costs.
Transmission at higher rates.
Secure data transmission.
Transportation becomes much easier.
Reduced cost of transportation.
Accidents will be completely absent.
Faster transportation.
You can be there when travel is impossible.
 The financial benefits are significant too.

15. Quantum Cryptography
Quantum cryptography allows the transmission of
information with 100% security ensured by the law of
physics.
Potential application for commerce and military
purpose.
Quantum Computer:
Computer that has data transmission rates many times
faster than today s most powerful computers.

16. CONCULSION:
So, while theoretically possible, scientists are pessimistic
about teleportation’s realistic feasibility. For now, it looks
like the only teleportation we’ll be seeing is on television
— but then again, never underestimate the ingenuity of
inventors and entrepreneurs.
It would be really cool to travel instantly to a far
destination like stars for example!!!!!
