MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

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.
