Atomic-State Teleportation Using GHZ State

Following the principle outlined by Karlsson and Bourennane [Phys. Rev. A 56, 5394(1998)], we propose an experimentally feasible scheme for the teleportation of an unknown atomic state among three high-Q cavities containing a nonlocal quantum superposition of microwave field states, in which the unknown atomic state can be completely teleported to either of two locations. This scheme can also be used for the teleportation of a cavity field in a superposition of zero-and one-photon Fock states.
