Abstract
We introduce an operational procedure to determine, with arbitrary probability and accuracy, optimal entanglement witnesses for every multipartite entangled state. This method provides an operational criterion for separability which is asymptotically necessary and sufficient. Our results are also generalized to detect all different types of multipartite entanglement.
摘要
我们引入一种操作程序，以任意概率和精度为每个多体纠缠态确定最优纠缠见证者。该方法提供了一种可分性的操作标准，它在渐近意义上是必要且充分的。我们的结果还被推广到检测所有不同类型的多体纠缠。
