改进的两方和多方纯化协议

Improved two-party and multi-party purification protocols

Elitza N. Maneva, John A. Smolin

摘要:

我们提出了一个改进的方案,用于纠缠纯化的二分混合态使用几个状态在一个时间,而不是在传统的递归方法的时间两个。我们还提出了一个推广的散列方法的n-部猫状态,它实现了有限产量的纯猫状态的任何所需的保真度。我们的结果进行了比较,以前的协议。

英文摘要:

We present an improved protocol for entanglement purification of bipartite mixed states using several states at a time rather than two at a time as in the traditional recurrence method. We also present a generalization of the hashing method to n-partite cat states, which achieves a finite yield of pure cat states for any desired fidelity. Our results are compared to previous protocols.
