多个Bell态副本的纠缠

The distillable entanglement of multiple copies of Bell states

Yi-Xin Chen, Dong Yang

摘要:

如果只提供一个拷贝,则不可能通过本地操作和经典通信(LOCC)来区分四个Bell状态。为了完成这项任务,两份副本就足够了,也是必要的。当提供$n$拷贝时,我们证明了可解纠缠正是$n-2$。

英文摘要:

It is impossible to discriminate four Bell states through local operations and classical communication (LOCC), if only one copy is provided. To complete this task, two copies will suffice and be necessary. When $n$ copies are provided, we show that the distillable entanglement is exactly $n-2$.
