摘要

摘要:冯·诺伊曼熵是信息论中最重要的物理量之一，对它的估计是近年来研究的一个课题。本文利用传输代价对Winter提出的无限维密度矩阵中冯诺依曼熵的一致连续性界进行了改进。

Improvement of the von Neumann entropy bound using the transport cost

Abstract The von Neumann entropy is one of the most relevant quantities in information theory, this makes it’s estimation a subject of research in the recent years. In the present paper we use the transport cost to make an improvement in the uniform continuity bound presented by Winter for the von Neumann entropy in infinite dimensional density matrices.
