4. 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.
 To avoid the problem of covering a physical distance
and to minimize the time, there are scientists working
right now on such a method of travel combining
properties of Telecommunication and transport a system
called Teleportation.

5. Teleportation
 Teleportation is made up of two words:
Telecommunication and Teleportation.
 Teleportation involves dematerialising an object at one
point, and sending the details of that object’s precise
atomic configuration to another location,where it’ll be
reconstructed.

6.  What this means is that the time
and space could be eliminated
from travel : we could be
transported to any location
instantly,without actucally
crossing a physical distance.

7.  In 1993, the idea of teleportation moved out of the realm
of science fiction and into the world of the theoritical
possibility.
It was then the physicist Charles Bannett and a team of
researchers at IBM confirmed that quantum teleportation
was possible,but only if the original object being
teleported was destroyed.

8.  Teleportation can be
explained with the
following terms :
1. Photon experiment
2. Human Teleportation
3. Quantum Teleportation

9. Photon Experiments
 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.)
 The Caltech group was able to read the atomic structure
of a photon, send this information across 3.28 feet
(about 1 meter) of coaxial cable and create a replica of
the photon.

10.  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.
 This principle states that you cannot simultaneously
know the location and the speed of a particle.
But if you can't know the position of a particle, then how
can you teleport it?
 In order to teleport a photon without violating the
Heisenberg Principle, the Caltech physicists used a
phenomenon known as entanglement.

11. Entanglement
 Entanglement means achieving the properties of one photon by
using another photon.
 In entanglement, at least three photons are needed to achieve
quantum teleportation:
1.Photon A: The photon to be teleported
2.Photon B: The transporting photon
3.Photon C: The photon that is entangled with photon B

12.  If researchers tried to look too closely at photon A
without entanglement, they would bump it, and thereby
change it.
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.

13. Principle Of Entanglement
 Two photons E1 and K and a beam
splitters (it splits a light into two equal
parts) are required
 We direct one of the entangled photons,
say E1, to the beam splitter.
 Meanwhile, we prepare another photon
with the polarization of 45 degree, and
direct it to the same beam splitter from
the other side, as shown

14.  The E1 photon incident from above
will be reflected by the beam splitter
some of the time and will be
transmitted some of the time.
Similarly for the K photon that is
incident from below. So sometimes
both photons will end up going up and
to the right as shown.
 Likewise, sometimes both photons will
end up going down and to the right

15.  However, in the case of one
photon going upwards and
the other going downwards,
we can not tell which is
which.
Perhaps both photons were
reflected by the beam
splitter, but perhaps both
were transmitted.
This means the two photons
have become entangled.

16. Human Teleportation
 For a person to be transported, a machine would have to be
built that can pinpoint and analyze all of the atoms that
make up the human body.
That's a more than a trillion-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, or the
person will arrive with some severe neurological or
physiological defect.

17. How it will be possible
 Teleportation would be combining genetic cloning with digitization.
In this bio-digital cloning , tele-travelers would have to die, in a
sense.
Their original mind and body would no longer exist. Instead, their
atomic structure would be recreated in another location, and
digitization would recreate the travelers' memories, emotions, hopes
and dreams.
So the travelers would still exist, but they would do so in a new
body, of the same atomic structure as the original body,
programmed with the same information.

19. Another Depiction of Human Teleportation
Process :

20. QUANTUM TELEPORTATION
 In quantum teleportation the original object is scanned in
such a way as to extract all the information from it, then
this information is transmitted to the receiving location
and used to construct the replica, not necessarily from
the actual material of the original, but perhaps from
atoms of the same kinds, arranged in exactly the same
pattern as the original. A teleportation machine would be
like a fax machine, except that it would work on 3-
dimensional objects as well as documents.

21.  it would produce an exact copy rather than an
approximate facsimile, and it would destroy the original
in the process of scanning it.
 In 1993 an international group of six scientists, including
IBM Fellow Charles H. Bennett, confirmed the intuitions
of the majority of science fiction writers by showing that
perfect teleportation is indeed possible in principle, but
only if the original is destroyed.

23.  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.

24. 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.

25.  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.

27.  This above figure compares conventional
facsimile transmission with quantum teleportation
(seen previously). In conventional facsimile
transmission the original is scanned, extracting
partial information about it, but remains more or
less intact after the scanning process.
 The scanned information is sent to the receiving
station, where it is imprinted on some raw
material (egg paper) to produce an approximate
copy of the original

28. THE THEORY BEHIND QUANTUM
TELEPORTATION:-
 A & B are two entangled particles created in
orthogonal state . C be the particle that we wish
to teleport . In order to cause an entanglement
between A & B, this simultaneously alters the
quantum state of B in such a way that when the
classical information gleaned from analysis of A
and C is applied to B , particle B becomes an
exact replica of C.In the meantime , C has been
totally disrupted and is no longer in it’s original
state

29. PRACTICAL APPLICATION:-
 Physicists can already teleport tiny things, such
as a beam of light or the angular spin of atomic
nuclei. But physicists caution that teleportation
research is still in the early development stage.
But within 20 years, Laflamme said teleportation
could be a fundamental step in the creation of
quantum computers, cryptography, and an
emerging technology called “superdense coding”
in which two quantum bits could be transmitted
for the price one.

30. Advantages of Teleportation:
 It’ll save a lot of time..(you’ll be at your destination in few seconds)
 It’ll be a really cheap process once it go mainstream.
 You don’t need to waste your money on buying an expensive cars
or booking airplane tickets…just buy a Teleporter instead.
 If there aren’t any fuel vehicles then there won’t be any Global
Warming...and there won’t be any apocalypse..
 Nobody will be late for anywhere…

31. Disadvantages of teleportation:
 The Only Disadvantage is that…it will make human-kind
Lazy…
and if there happens to be any technical difficulty..one
might end up losing his/her Life..or looking like a freak…
Don’t worry..there won’t be any,because..they’ll test it on
animals first…just like old school sci-fi movies…

32. 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.
