 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

 Step

1= Making an exact copy of the material make up of the object being transported.  Step 2= Transporting this copy to a different location.  Step 3= Destroying of the original object.

Teleportation what’s the problem?

Problem: Matter cannot be reversibly converted into light!

Question: If matter not teleported, then what is being transmitted?

Answer: information - is what should be transmitted

 Classical

teleportation taking fax machine as example

The more precisely the position is determined, the less precisely the momentum is known in this instan and vice versa. --Heisenberg 1927

Blegdamsvej 17, Copenhagen

Heisenberg in 1927. Minimal symmetric Uncertainty:

1 Var ( x ) = ∂x = ∂p = 2 2

Noncommuting operators:

ˆ,P ˆ] = [X i

 One

scan out part of information from object A (the original).

 Two

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

 At

the sending station the object B is scanned with the original object A.

 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 to the receiving station.

 Object

state.

A itself not in its original



The only thing teleported is the photon’s polarization state or more generally, its quantum state, not the photon “itself.”



Entangle photon A with photon X, photon X loses all memory, its original state. As a member of an entangled pair, it has no individual polarization

PHOTON TELEPORTATION

 In

Quantum Mechanics, it sometimes occurs that a measurement of one particle will effect the state of another particle, even though classically there is no direct interaction

 When

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

Y1 − Y2 = 0,

 Quantum

Entanglement’s role in teleporting

 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.  "The Philadelphia Experiment“ On October 28, 1943 by US NAVY US Navy ship was invisibly teleported from Philadelphia to

 In

2002, researchers at the Australian National University successfully teleported a laser beam.

 On

October 4, 2006 at the Niels Bohr Institute in Copenhagen, Denmark. Dr. Eugene Polzik and his team teleported information stored in a laser beam into a cloud of atoms.

The human body consist of 1028 atoms. So we have to teleport these atoms with exact precision. A duplicate of the person would be made at the other end. Original mind and body no longer exists, their atomic structure would be recreated at the other end. But there are some limitations:

By reconstruction we may obtain the body, but can be a dead body  Since a large quantity of information has to be teleported, it will take years to teleport a man. 

 If

teleportation be possible it become the fastest means of Communication.  Tremendous amount of chemicals are now shipped from one location to another.  This teleportation can be used in military purpose for data Encryption  Space exploration can be enhanced. We cam teleport machinery to space shuttles or space colonies. Fuels for space stations can also be teleported  Colonizing in mars is not possible today due to the lack of fresh water, if we can teleport water directly from earth colonizing in mars is possible

 The

basic data unit in a quantum computing is a qubit.  In a single qubit it is possible to carry lot of zeros and ones all together.  quantum computers have the potential ability to carry and process large amounts of information in parallel and at very high speeds.

 Unlike

a classical bit, which is definitely in either state, the state of a Qubit is in general a mix of |0> and |1>.

 For

convenience, we will use the matrix representation 1  0 0 =   1 =    0 1

A

Quantum Logic Gate is an operation that we perform on one or more Qubits that yields another set of Qubits.

 As

in classical computing, the NOT gate returns a 0 if the input is 1 and a 1 if the input is 0.  The matrix representation is

0 1   1 0

 Other

gates include the HadamardWalsh matrix: 1 1 1    2 1 −1

 And

Phase Flip operation:

1 0    iϕ  0 e 
