我们证明了在腔QED中，一个真正的六原子纠缠态可以用来实现任意两原子态的确定性量子态共享。在我们的方案中，两个主体中的任何一个都有能力重建原始状态，条件是他/她得到另一个的帮助，但其中一个没有得到任何信息。所提出的协议被证明是安全的，对某些窃听攻击。
We demonstrate that a genuine six-atom entangled state can be used to realize the deterministic quantum state sharing of an arbitrary two-atom state in cavity QED. In our scheme, any one of the two agents is sufficient to reconstruct the original state only under the condition that he/she obtains the help of the other one, but one of them obtains no information. The presented protocol is showed to be secure against certain eavesdropping attacks.
