作为局部伪混合的量子不可分性
Quantum inseparability as local pseudomixture
摘要：
我们展示了如何分解任何密度矩阵的最简单的二元复合系统，无论是可分离的或不，在只有产品向量。我们确定的所有情况下，这样的分解所需的产品向量的最小数量。可分离态对应于从一个到四个纯产物态的混合。不可分的状态可以被描述为四个或五个纯产物状态的伪混合物，并且可以通过将它们与一个或两个纯产物状态混合来使其可分离。
英文摘要：
We show how to decompose any density matrix of the simplest binary composite systems, whether separable or not, in terms of only product vectors. We determine for all cases the minimal number of product vectors needed for such a decomposition. Separable states correspond to mixing from one to four pure product states. Inseparable states can be described as pseudomixtures of four or five pure product states, and can be made separable by mixing them with one or two pure product states.
