论文摘要
真正的多部分纠缠在量子信息处理中起着重要作用。在量子纠缠理论中，很长一段时间以来，对真正的多部分纠缠的检测一直是一个具有挑战性的问题。我们提出了一个基于量子Fisher信息来检测任意维三方状态的真正三方纠缠的标准。我们表明，通过详细的例子，该标准对于某些州检测真正的三方纠缠更为有效。
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.
