A Note on Quantum Entanglement and PPT

Shao-Ming Fei and Xianqing Li-Jost

Abstract

We study quantum states for which the PPT criterion is both sufficient and necessary for separability. We present a class of 3 x 3 bipartite mixed states and show that these states are separable if and only if they are PPT.
