Teleportation of atomic states within cavities in thermal states - art. no. 044302

A scheme is proposed for the teleportation of atomic states within cavities . The scheme is insensitive to the cavity field states and cavity decay. Th e teleportation may be achieved in a simple way. We show how the idea can b e used to generate multiatom entangled states. In order to entangle it atom s, we require n - 1 cavities and allow the first cavity to exchange energy with the environment. The other n - 2 cavities are always in the vacuum sta te and thus the cavity decay is suppressed.
