论文摘要
众所周知，部分纠缠/可分离性违反了有关凸出船体和交叉路口的操作的分配规则。在本说明中，我们给出了由分布式规则以及相应证人引起的三个Qubit部分纠缠状态的标准。该标准将以对角线和抗对角线的条目给出。实际上，当所有条目为零时，除了对角线和反对基条件时，它们实际上完全表征了这些部分纠缠。 Greenberger-Horne-Zeilinger对角状态等重要状态在此类中落下。
It is known that the partial entanglement/separability violates distributive rules with respect to the operations of taking convex hull and intersection. In this note, we give criteria for three qubit partially entangled states arising from distributive rules, together with the corresponding witnesses. The criteria will be given in terms of diagonal and anti-diagonal entries. They actually characterize those partial entanglement completely when all the entries are zero except for diagonal and anti-diagonal entries. Important states like Greenberger-Horne-Zeilinger diagonal states fall down in this class.
