提出一个利用三粒子非最大纠缠态传送未知原子态的腔QED方案.这个方案的主要优点是隐形传态和纯化过程能够同时进行,而且与腔衰减和热场无关,不用预先将非最大纠缠态量子通道纯化为最大纠缠态.另外,联合Bell态测量可以转化为单原子测量.
A physical scheme for teleporting unknown atomic entangled states via three-atom non-maximally entangled states is proposed in cavity QED. The distinct advantages of the scheme are that the teleportation and distillation procedure can be realized simultaneously, and the scheme is insensitive to the cavity decay and thermal field with the assistance of a strong classical driving field. It is also unnecessary to concentrate non-maximally entanglement state quantum channel in advance. In addition, the joint Bell-state measurement can be distinguished via detecting the atomic state.
