Abstract

We propose a quantum extension of the Markov-Dobrushin inequality. As an application, we estimate the Markov-Dobrushin constant for some classes of quantum Markov channels, in particular for the Pauli channel, widely studied in quantum information theory.

量子信道的Markov-Dobrushin不等式

我们提出了Markov-Dobrushin不等式的量子推广。作为应用，我们估计了一些量子马尔可夫信道的马尔可夫-多布鲁申常数，特别是在量子信息论中广泛研究的泡利信道。

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.
