INTRODUCTION
Teleportation appears in scientific fiction where object disappears at one place and appears at some other place.
Dream of beaming of objects from place to place is now reality for particles of light.
Entangled systems are shared by sender and receiver.
Scientists who paved the way for quantum teleportaion.
ENTANGLEMENT
Entanglement means achieving the properties one photon by another photon.
Here photon A and photn B will be same.
In entanglement, at least three photons are needed to achieve 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
ENTANGLED PHOTONS AT WORK
Delicate entangled state is not disturbed.
Alice the sender and Bob the receiver share pair of entangled particles A and B.
Bob get a perfect replica of Alice.
PRINCIPLE OF ENTANGLEMENT & BELL STATE MEASUREMENTS
Two photons E1 & 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.
