准自由费米子的纠缠蒸馏

Entanglement distillation from quasifree Fermions

Zoltan Kadar, Michael Keyl, Dirk Schlingemann

摘要:

我们提出了一个从任意准自由态的两体费米系统中提取纠缠的方案。它可以应用于包含无限单副本纠缠的系统,或者可以使用任意数量的同等准备的系统。我们表明,所提出的计划的效率一般是非常好的,在某些情况下,甚至是最佳的。此外,我们还将其应用于费米子在无限晶格上的跳跃,并证明了在这种情况下,对于多于10^6个晶格位置,有效的数值分析是可能的。

英文摘要:

We develop a scheme to distill entanglement from bipartite Fermionic systems in an arbitrary quasifree state. It can be applied if either one system containing infinite one-copy entanglement is available or if an arbitrary amount of equally prepared systems can be used. We show that the efficiency of the proposed scheme is in general very good and in some cases even optimal. Furthermore we apply it to Fermions hopping on an infinite lattice and demonstrate in this context that an efficient numerical analysis is possible for more then 10^6 lattice sites.
