Teleportation of atomic states within cavities in thermal states
Shi‐Biao Zheng, Guang‐Can Guo · Physical Review A · 2001
A scheme is proposed for the teleportation of atomic states within cavities. The scheme is insensitive to the cavity field states and cavity decay. The teleportation may be achieved in a simple way. We show how the idea can be used to generate multiatom entangled states. In order to entangle n atoms, we require $n\ensuremath{-}1$ cavities and allow the first cavity to exchange energy with the environment. The other $n\ensuremath{-}2$ cavities are always in the vacuum state and thus the cavity decay is suppressed.
