摘　　要：本文提出一种单原子态的可控的量子隐形传态的腔QED方案。本方案利用了原子与腔肠相互作用的大失谐模型,因而对腔场衰减引起的退相干不敏感。本方案同时引入了执行控制任务的第三方,因而只有在第三方的协同合作下,接收者才能够有效地恢复原来的原子态信息。最后,对该方案的试验实现的可能性做了讨论。A controlled teleportation scheme for single atomic quantum state is proposed in cavity QED. The scheme is based on the large detuning interaction of the atom-cavity system, therefore, it is not insensitive to the decoherence induced by cavity decay. The scheme also incorporates a third party to control the process, and only with the cooperation of the third party, the receiver can successfully reconstruct the original atom state. Finally, the feasibility of the experimentally realization of the scheme is also discussed.
