摘要

在广义各向同性状态族中测试了基于相关张量的可分性准则的检测能力[公式:见文]。对于[公式:见文本]，所有这些标准都弱于正部分转位(PPT)标准。有趣的是，我们的分析支持了最近的一个猜想，即基于对称信息完备的正算子值测度(SIC-POVMs)的准则比重新调整准则更强。

Detection Power of Separability Criteria Based on a Correlation Tensor: A Case Study

Detection power of separability criteria based on a correlation tensor is tested within a family of generalized isotropic states in [Formula: see text]. For [Formula: see text] all these criteria are weaker than the positive partial transposition (PPT) criterion. Interestingly, our analysis supports the recent conjecture that a criterion based on symmetrically informationally complete positive operator-valued measure (SIC-POVMs) is stronger than realignment criterion.

期刊介绍： The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication, filtering, memory and cooperative behaviour, etc., in open complex systems.
