| 摘 要： | 提出了一个利用原子与腔场相互作用实现原子纠缠纯化的方案,并将该方法推广到多原子部分纠缠的情况.计算结果表明,对不同原子数的部分纠缠态,纯化的概率都为2b2.该方案的主要优点是只需引入一个辅助腔场,然后进行局域操作就能实现原子的纠缠纯化,这在实验上是简单可行的.

| Abstract: | A physical scheme for atomic entangled states distillation is proposed via atom-cavity field interaction.Which is generalized to non-maximally entangled multi-atom states distillation.It is found from calculation outcome that the distillation probabilities of all kinds of entangled atomic states are the same, 2b 2.The advantage of the scheme is entangled distillation is realized through only introducing an auxiliary cavity and making a local operation.The scheme is simple and feasible in experiment. |
