QUANTUM MECHANICS:
Teleportation Beams Up a Photon's State

Andrew Watson

Researchers at the University of Innsbruck in Austria have shown that part of the spin orientation of a photon of light can be transferred instantaneously to another photon, irrespective of distance. This work is being called the first experimental demonstration of quantum teleportation--the transfer of a quantum state from one particle to another, first proposed by IBM's Charles Bennett and his collaborators in 1993. Quantum teleportation could have applications in quantum computing, say researchers, such as in constructing stable memories, protecting delicate quantum states, and communicating between quantum computers.
