提出了一种在空腔内实现原子态隐形传态的方案。该方案对腔场状态和腔衰减不敏感。传送可以用一种简单的方法实现。我们展示了如何使用这个想法来产生多原子纠缠态。为了纠缠n个原子，我们需要$n\ensuremath{-}1$空腔，并允许第一个空腔与环境交换能量。另外$n\ensuremath{-}2$空腔始终处于真空状态，因此空腔衰减受到抑制。
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.
