Teleportation with atoms.

The teleportation of an atomic state accomplishes the complete transfer of information from one particle to another, employing the non-local properties of quantum mechanics. Recently, two groups have achieved the deterministic teleportation of a quantum state between a pair of trapped ions. Following closely the original proposal of Bennett et al., a highly entangled pair of ions is created, a complete Bell-state projective measurement involving the source ion and one of the entangled pair is carried out, and state reconstruction conditioned on this measurement is performed on the other half of the entangled pair. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
