摘要

我们分析了矩阵代数中正映射的Kadison-Schwarz近似。这是纠缠理论中使用的著名的正映射的结构物理近似的一个类似。我们研究了几种已知的可分解图(如换位图)和不可分解图(如Choi图及其推广)。

On Kadison-Schwarz Approximation to Positive Maps

We analyze Kadison-Schwarz approximation to positive maps in matrix algebras. This is an analogue of the well known structural physical approximation to positive maps used in entanglement theory. We study several known maps both decomposable (like transposition) and non-decomposable (like Choi map and its generalizations).

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.
