基于新的不可分解准则的不可分解正映射的构造
Constructions of indecomposable positive maps based on a new criterion for indecomposability
摘要:
给出了Hilbert空间上算子空间上的正映射不可分解的一个判别准则。我们证明了这一准则可以应用于两类正映射。这些映射族可以用来形成二分量子态的可分性判据,从而可以检测束缚纠缠量子态的纠缠。
英文摘要:
We give a criterion for a positive mapping on the space of operators on a Hilbert space to be indecomposable. We show that this criterion can be applied to two families of positive maps. These families of maps can then be used to form separability criteria for bipartite quantum states that can detect the entanglement of bound entangled quantum states.
