Teleportation involvesdematerializing an object at onepoint, and sending the details of thatobject's precise atomic configurationto another location, where it will bereconstructed.

What this means is that time andspace could be eliminated fromtravel -- we could be transported to

any location instantly, without


4/28

Step 1= Making an exact copy of thematerial make up of the object being

transported.Step 2= Transporting this copy to a

different location.Step 3= Destroying of the original

object.

Teleportation whats the problem?Tele

portation whats the problem?

Problem: Matter cannot be reversiblyconverted into light!

Question: If matter not teleported, then

what is being transmitted?

Answer: information - is what should be transmitted

The more precisely the position is determined,the less precisely the momentum is known in this instaand vice versa.

One scan out part of informationfrom object A (the original).

Two objects B&C are prepared andbrought in contact (i.e., entangled)and then separated.

At the sending station the object B isscanned with the original object A.


9/28

While causing the remaining,unscanned,part of the information in

A to pass, via EPR entanglement,into another object C.

This scanned information is sent tothe receiving station.

Object A itself not in its original

state.

PHOTONTELEPORTATION

The only thing teleportedis the photonspolarization state ormore generally, its

quantum state, not thephoton itself.

Entangle photon A with

photon X, photon X losesall memory, its originalstate.

As a member of anentangled pair, it has no

individual polarization


12/28

In Quantum Mechanics, it sometimesoccurs that a measurement of one

particle will effect the state ofanother particle, even thoughclassically there is no directinteraction

When this happens, the state two ofthe particles is said to be entangled.

In 1998, physicists at theCalifornia Institute of Technology(Caltech), along with two European

groups, turned the IBM ideas intoreality by successfully teleportinga photon.

In 2002, researchers at theAustralian National University

successfully teleported a laser beam.

On October 4, 2006 at the Niels BohrInstitute in Copenhagen, Denmark.Dr. Eugene Polzik and his teamteleported information stored in alaser beam into a cloud of atoms.

19/28

The human body consist of 1028 atoms. Sowe have to teleport these atoms with exactprecision. A duplicate of the person wouldbe made at the other end.

Original mind and body no longer exists,their atomic structure would be recreatedat the other end. But there are somelimitations:

By reconstruction we may obtain the body,but can be a dead body

Since a large quantity of information has tobe teleported, it will take years to teleport a

man.


20/28

If teleportation be possible it become thefastest means of Communication.

Tremendous amount of chemicals are nowshipped from one location to another.

This teleportation can be used in militarypurpose for data Encryption

Space exploration can be enhanced. Wecam teleport machinery to space shuttles

or space colonies. Fuels for space stationscan also be teleportedColonizing in mars is not possible today

due to the lack of fresh water, if we canteleport water directly from earthcolonizing in mars is possible

The basic data unit in a quantumcomputing is a qubit.

In a single qubit it is possible to carrylot of zeros and ones all together.quantum computers have the

potential ability to carry and processlarge amounts of information inparallel and at very high speeds.


22/28

Unlike a classical bit, which isdefinitely in either state, the state ofa Qubit is in general a mix of |0>

and |1>.For convenience, we will use the

matrix representation

A Quantum Logic Gate is anoperation that we perform on

one or more Qubits thatyields another set of Qubits.

As in classical computing, the NOTgate returns a 0 if the input is 1 and

a 1 if the input is 0.The matrix representation is
