摘要

摘要: 研究了一类 55 的两体量子态, 证明其可分的充分必要条件是它的部分转置矩阵为半正定矩阵~(PPT), 并且构造出了这类可分态的一种可分分解表示. 用此方法, 可判别一类量子态是否纠缠.

Abstract: This paper studied certain quantum states for which the PPT criterion was both sufficient and necessary for separability. A class of 55, bipartite mixed states was prestented and the conditions of PPT for these states were derived. The separable pure state decompositions of these states were explicitly constructed when they were PPT, so we can judge a class of states entangled or not by this method.
