| 摘 要： | 近年来的研究表明,非局域关联可以以无通信关联盒子的形式被蒸馏。目前人们广泛讨论了两方两输入两输出盒子的非局域关联的蒸馏,提出了几种蒸馏方案。我们将这几种蒸馏方案推广到三方盒子,发现三方盒子的非局域关联也可以被蒸馏;并将三方盒子蒸馏方案的效率与两方盒子蒸馏方案的效率进行对比,发现其蒸馏效果低于对两方盒子的蒸馏。

| Abstract: | Recent advances on nonlocality show that nonlocal correlations in the form of non-signaling correlated boxes can be distilled.The bipartite binary-inputs and binary-outputs non-signaling correlated boxes were widely discussed,and several efficient protocols were presented to distill them.In this paper,we generalize these bipartite distillation protocols to the tripartite cases.We find that the BS protocol(by N.Brunner and P.Skrzypczyk) for bipartite system still works in tripartite cases,but has a less efficiency than in bipartite system. |
