论文摘要
这是一个有趣的问题，是基于两个双方纠缠状态的集体使用来构建真正的三方纠缠状态。我们认为各州是两分的Werner国家，我们构建了Werner国家参数的间隔，使三方状态是真正的纠结。此外，我们介绍了使用实验中当前技术检测三方真实纠缠的方法。我们还研究了真正的多部分纠缠并发的下限。
It is an interesting problem to construct genuine tripartite entangled states based on the collective use of two bipartite entangled states. We consider the case that the states are two-qubit Werner states, we construct the interval of parameter of Werner states such that the tripartite state is genuine entangled. Further, we present the way of detecting the tripartite genuine entanglement using current techniques in experiments. We also investigate the lower bound of genuine multipartite entanglement concurrence.
