| Abstract: | We propose a controlled scheme for teleportation of an arbitrary oneor two atomic state via a driven QED cavity. The scheme does notinvolve the joint Bell-state-measurement BSM and the probabilityof successful teleportation is 1. We show that the original atomicstate cannot be perfectly restored by the receiver without all theagents collaborate and classical communication. |
