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.
Yet each of these forms of transportation share the same flaw:
They require us to cross a physical distance.
A technique which combines the properties of
telecommunications and transportation to achieve a system for
travelling is called Teleportation.

5. About Teleportation
The Teleportation system is unique and has been designed to
enable a life-size image of a person to appear within a 3D
environment.
It enables to make eye contact with individuals, use props and
hold true two-way conversations .
It allows to communicate naturally with anyone or any group of
people anywhere in the world - people achieve a sense of
presence that cannot be gained from any other technology.

6. Types of Teleportation
Basically there are two types of Teleportation
1. Classical Teleportation
2. 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.

7. Steps involved
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.
4. A rough example of classical teleportation is Fax technology.

8. Classical Facsimile Transmission
 Pictorial Representation
Original
Scan
Intact Original
Raw material
Apply Treatment
Approximate copy
Send data

9. Quantum Teleportation
Quantum teleportation is the making of an object or person
disintegrate at one place while a perfect replica appears
somewhere else.
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.
It would produce an exact copy rather than an approximate
facsimile, and it would destroy the original in the process of
scanning it.

10. Quantum Teleportation
 Pictorial Representation

11. Heisenberg Uncertainty Principle –
A barrier in Teleportation
1. This principle states that you cannot simultaneously measure
the position and the velocity of a quantum particle.
2. Measurement of one value changes the other value
accordingly.
In order to teleport a photon without violating the Heisenberg
Principle, a phenomenon is used known as “Entanglement”.

12. Photon Experiment - A Proven Technology
In 1998, physicists at the California Institute of Technology
(Caltech), along with two European groups, turned the ideas into
reality by successfully teleporting a Photon.
The Caltech group was able to read the atomic structure of a
photon, send this information across 1 meter of coaxial cable and
create a replica of the photon.
A more recent teleportation success was achieved at the
Australian National University, when researchers successfully
teleported a laser beam.

13. Human Teleportation
The technology which explains human teleportation is called “Bio-
digital Cloning”.
In bio-digital cloning the original mind and body of the Tele-
traveller would no longer exist. Instead, their atomic structure
would be recreated in another location.
And digitization would recreate the travellers’ memories,
emotions, hopes and dreams.
So the travellers' 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.

14. Advantages
Substantial savings in travel and accommodation costs.
There is natural two-way communication with no audio
interference or discernable latency even if the communication
is across twelve time zones.
Less non productive travel time means more efficient use of
your valuable time and human resources.
You can be there when travel is impossible.

15. Conclusion
Difficult to fathom what is future of human teleportation.
Development of Quantum computer, Suspended animation and
Backup copies are possible using Teleportation.
We are away from being able to Teleport and entangle bulky
objects.
