Long distance, unconditional teleportation of atomic states via complete Bell state measurements

Phys Rev Lett. 2001 Oct 15;87(16):167903. doi: 10.1103/PhysRevLett.87.167903. Epub 2001 Sep 27.


We propose a scheme for creating and storing quantum entanglement over long distances. Optical cavities that store this long-distance entanglement in atoms could then function as nodes of a quantum network, in which quantum information is teleported from cavity to cavity. The teleportation is conducted unconditionally via measurements of all four Bell states, using a novel method of sequential elimination.
