摘要:

真实的多体纠缠在量子信息处理中起着重要的作用。真实多体纠缠的检测一直是量子纠缠理论中的一个具有挑战性的问题。基于量子费舍尔信息,提出了一个检测任意维三重态真实纠缠的判据。我们通过具体的例子说明了这个判据对某些态检测真正的三重纠缠更为有效。

英文摘要:

Genuine multipartite entanglement plays important roles in quantum information processing. The detection of genuine multipartite entanglement has been long time a challenging problem in the theory of quantum entanglement. We propose a criterion for detecting genuine tripartite entanglement of arbitrary dimensional tripartite states based on quantum Fisher information. We show that this criterion is more effective for some states in detecting genuine tripartite entanglement by detailed example.
