摘要
从两对原子的纠缠态出发 ,通过对单原子的局域测量 ,实现了纠缠的纯化 该方案不同于一般的通过联合的Bell基测量而实现纠缠纯化的过程 在此方案里 ,纯化包含两方面的含义 。
From four atom entangled state,entanglement purification is realized through a single atom local measurements Our method is different from general one of a joint Bell basis measurement In our scheme,the purification include two meanings (1)four atom entanglement is purified into two atom entangled states;(2)some two atom entanglements are the maximal entangled states Finally,a scheme for preparing four atom entangled state is proposed
