Abstract:
We study certain quantum states for which the PPT criterion is both sufficient and necessary for separability. We present a class of formula8, formula10, bipartite mixed states and derive the conditions of PPT for these states. The separable pure state decompositions of these states are explicitly constructed when they are PPT.
