Separable State Decompositions for a Class of Mixed States

Ting-Gui Zhang, Xiaofen Huang, Xianqing Li-Jost, Naihuan Jing and Shao-Ming Fei

Abstract

We study certain quantum states for which the PPT criterion is both sufficient and necessary for separability. A class of $n\times n$ bipartite mixed states is presented and the conditions of PPT for these states are derived. The separable pure state decompositions of these states are explicitly constructed when they are PPT.
