A simplification of entanglement purification

Jin-Yuan Hsieh, Che-Ming Li, Der-San Chuu

摘要:

提出了一种混合映射的思想来建立标准的纠缠纯化协议,该协议通过标准的本地纯化操作和经典通信,保证将任意可纠缠态纯化到期望的最大纠缠纯态.在这项工作中提出的协议,其中使用两个状态转换,比IBM和牛津协议在这个意义上,他们需要更少的操作时间,产生相同数量的所需的纯状态,执行更好。在这项工作中提出的协议之一,甚至可以导致一个更高的提高输出产量时,它与哈希协议相结合,相比,牛津和哈希协议组成的组合算法。

英文摘要:

An idea of hybrid maps is proposed to establish standard entanglement purification protocols which guarantee to purify any distillable state to a desired maximally entangled pure state all by the standard purification local operations and classical communications. The protocols proposed in this work, in which two state transformations are used, perform better than the IBM and Oxford protocols in the sense that they require fewer operation times in yielding a same amount of the desired pure state. One of the proposed protocol in this work can even lead to a higher improved output yield when it is combined with the hashing protocol, as compared with the combined algorithm consisting of the Oxford and the hashing protocol.
