2. Technology that will change our lives
• Think of a world were you can teleport/send a whole 3D-matter to a distant place similar to
what we do in fax.
• Think what if you can send a gift like spectacles to your grandmother who is in a different
city/country.
• Think what if you can travel from one place to another without actually moving to the place
by rail/road/air.
• Watched science-fiction movies like Doom, Jumper, Stargate, Star Trek, X-Men, Men in
Black, The Transformers , Harry Potter, Power Rangers, etc?

3. What is Teleportation?
Teleportation is the name given by science fiction writers to
the feat of making an object or person disintegrate in one
place while a perfect replica appears somewhere else.

4. Why the word ‘Quantum’ before Teleportation?
• Every matter is made up of atoms or photons.
• Teleportation deals with information carried out by these atoms or
photons.
• To collect information out of these atoms or photons, one has to deal with
Quantum Mechanics.
• Hence, the name Quantum Teleportation.

5. Can it be a reality?
• In the past, the idea of teleportation
was not taken very seriously by
scientists, because it was thought to
violate the uncertainty principle of
quantum mechanics.
• In 1993 an international group of
scientists and researchers at IBM
confirmed that perfect teleportation
is indeed possible in principle, but
only if the original is destroyed.

6. How to accomplish Quantum Teleportation?
• The general idea seems to be that 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 to construct
the replica.
• The replica need not necessarily be from the actual material of the
original, but perhaps from atoms of the same kinds, arranged in exactly
the same pattern as the original.

7. How teleportation machine will look?
• A teleportation machine would be like a fax machine.
• It would work on 3-dimensional objects as well as documents.
• It would produce an exact copy rather than an approximate facsimile, and
it would destroy the original in the process of scanning it.

8. Can we really teleport human?
• Theoretically YES.
• Practically NO: How to replicate our soul is a big problem in the way.
• Quantum teleportation is unrelated to the kind of teleportation commonly
used in fiction,
– as it does not transport the system itself
– does not function instantaneously
– and does not concern rearranging particles to copy the form of an object.
Thus, despite the provocative name, it is best thought of as a kind of
communication, rather than a kind of transportation.

9. The Concept
• 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, via the
Einstein-Podolsky-Rosen effect,
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.

10. Other benefits of Teleportation
• Long range quantum communication ultimately
leading to a "quantum internet“.
• Building of a practical working quantum computer.
• Space exploration.

11. Progress so far
• The seminal paper first expounding the idea was published by six scientists
in 1993.
• Since then, quantum teleportation has been realized in various physical
systems.
• Presently, the record distance for quantum teleportation is 143 km (89 mi)
with photons and 21m with material systems.
• On September 11th 2013, the Furusawa group at the University of Tokyo
succeeded in demonstrating complete quantum teleportation of photonic
quantum bits by a hybrid technique for the first time worldwide.
