Quantum physics: Push-button teleportation
H. J. Kimble1 & S. J. van Enk2
Abstract
Two groups have succeeded in teleporting quantum states between different atoms — a spectacular advance in the quest to achieve quantum computation.
In 1993, Charles Bennett and colleagues described a remarkable protocol for transporting a quantum state from one location to another1, a protocol that succeeds even when the quantum state is completely unknown at the respective sites. Such quantum teleportation makes use of an extraordinary quantum resource, namely entanglement between two systems.
