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.

Separable State Decompositions for a Class of Mixed States

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

Abstract

We study certain quantum states for which the PPT criterion is both sufficient and necessary for separability. We present a class of $(2k+1)\times (2k+1)$, $k\in \Bbb{N}$, 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.
