Teleportation involves transferring the quantum information of an object to another location without physically moving the object through space. Scientists have successfully teleported photons and quantum information between light and matter. While teleporting an entire human is extremely challenging due to the vast number of quantum bits needed to describe a person, scientists continue to improve teleportation techniques and it may one day be possible to teleport larger objects like humans. Teleportation could enable instant travel and has applications in quantum computing and cryptography.

3. Introduction
 •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.
 Bicycle,Bus,Train,Aireoplane,…..
 The above require physical distance where it can take lot of time to travel.
 • To avoid the problem of covering a physical distance and to minimise the time
,there are scientists working right now on such a method of travel, combining
properties of telecommunications and transportation to achieve a phenomenon
called teleportation

4. Once imagine if there
is a chance that we can
travel from one place
to another place
without covering the
actual physical
distance.

5. What is Teleportation ?
 Teleportation involves dematerializing an object at one point, and sending the details
of that object's precise atomic configuration to another location, where it will be
reconstructed.
 What this means is that time and space could be eliminated from travel -- we could be
transported to any location instantly, without actually crossing a physical distance.
 In 1993, the idea of teleportation moved out of the realm of science fiction and into
the world of theoretical possibility. It was then that physicist Charles Bennett and a
team of researchers at IBM confirmed that quantum teleportation was possible, but
only if the original object being teleported was destroyed.
 This revelation, first announced by Bennett at an annual meeting of the American
Physical Society in March 1993

6. Any real examples
for Teleportation

7.  In 1998, physicists at the California Institute of Technology (Caltech), along with
two European groups, turned the IBM ideas into reality by successfully teleporting
a photon, a particle of energy that carries light.
 In performing the experiment, the Caltech group was able to get around the
Heisenberg Uncertainty Principle, the main barrier for teleportation of objects
larger than a photon.

8. Heisenberg
Uncertainty
Principle
THIS PRINCIPLE STATES THAT YOU CANNOT
SIMULTANEOUSLY KNOW THE LOCATION AND
THE SPEED OF A PARTICLE.
THE MORE ACCURATELY AN OBJECT IS
SCANNED, THE MORE IT IS DISTURBED BY THE
SCANNING PROCESS ,UNTIL ONE REACHES A
POINT WHERE THE OBJECT’S ORIGINAL
STATUS HAS BEEN COMPLETELY DESTROYED
,STILL THAT WE CANNOT MAKE A PERFECT
REPLICA.
IN ORDER TO TELEPORT A PHOTON WITHOUT
VIOLATING THE HEISENBERG PRINCIPLE, THE
CALTECH PHYSICISTS USED A PHENOMENON
KNOWN AS ENTANGLEMENT.

9. ENTANGLEMENT
 Entanglement means achieving the properties one photon by another photon.
 In entanglement, at least three photons are needed to achieve teleportation:
 Photon A:The photon to be teleported
 Photon B:The transporting photon
 Photon C:The photon that is entangled with photon B

10.  If researchers tried to look too closely at photon A without entanglement, then the
photon will be destructed because of full scanning.
 By entangling photons B and C, researchers can extract some information about
photon A, and the remaining information would be passed on to B by way of
entanglement, and then on to photon C.
 When researchers apply the information from photon A to photon C, they can
create an exact replica of photon A.
 However, photon A no longer exists as it did before the information was sent to
photon C.

11.  This six scientists found a way to scan out part of the information from an object
A, which one wishes to teleport, while causing the remaining, unscanned, part of
the information to pass, into another object C which has never been in contact
with A.
 Later, by applying to C a treatment depending on the scanned-out information, it
is possible to maneuver C into exactly the same state as A was in before it was
scanned.
 A itself is no longer in that state, having been thoroughly disrupted by the
scanning, so what has been achieved is teleportation, not replication.

12. Teleportation of
Photon
As the figure above
suggests, the unscanned
part of the information is
conveyed from A to C by
an intermediary object B,
which interacts first with C
and then with A.

13.  In quantum teleportation two objects B and C are first brought into contact and
then separated.
 Object B is taken to the sending station, while object C is taken to the receiving
station.
 At the sending station object B is scanned together with the original object A
which one wishes to teleport, yielding some information and totally disrupting the
state of A and B.
 The scanned information is sent to the receiving station, where it is used to select
one of several treatments to be applied to object C, thereby putting C into an
exact replica of the former state of A

14. Real Teleportation Experiments
 In 2002 the Australian national University team successfully teleported a laser beam.
 In oct 4 2006 at the Niels Bhor Institute in the Copenhagen,Denmark Dr.Polizik and his
team Successfully teleported the information present in the beam in to a cloud of
atoms.
 It involves teleportation between light and matter.
 The Philadelphia Experiment is an alleged military experiment supposed to have
been carried out by the U.S. Navy at the Philadelphia Naval
Shipyard in Philadelphia, Pennsylvania, United States, sometime around October 28,
1943.
 The destroyer escort USS Eldridge was rendered invisible, teleported to New York,
teleported to another dimension where it encountered aliens, and teleported through
time, resulting in the deaths of several sailors

15. Real Applications
 Quantum Cryptography
Quantum Cryptography allows the transmission of with 100% security ensured
by the law of physics .these are the potential applications for the military and
commerce.
 Quantum Computation
computer Performance, memory and functions are increasing for every
18months as the size remains same means we are expecting more and more with the
fewer and fewer atoms .Eventually classical physics is no longer exists.

16. How hard is it to
teleport a human?
1.THERE IS ABOUT 10
(1,000,000,000,000,000,000,000,000,0
00) ATOMS IN A PERSON.
2.WITH 100 PARAMETER PAIRS PER
ATOM, THAT’S ABOUT 10 PAIR OF
INFORMATION.
3. SO FAR WE HAVE DONE 1 PAIR,
SO A HUMAN IS ABOUT 10 TIMES
HARDER.

18. Conclusion
 But like all technologies, scientists are sure to continue to improve upon the ideas
of teleportation, to the point that we may one day be able to avoid such harsh
methods.
 • One day, one of our descendents could finish up a work day at a space office
above some far away planet in a galaxy many light years from Earth, tell his or her
wristwatch that it's time to beam home for dinner on planet X below and sit down
at the dinner table as soon as the words leave his mouth
