Abstract

In this paper, we analyze the classical capacity of the generalized Pauli channels generated via memory kernel master equations. For suitable engineering of the kernel parameters, evolution with non-local noise effects can produce dynamical maps with a higher capacity than a purely Markovian evolution. We provide instructive examples for qubit and qutrit evolution. Interestingly, similar behavior is not observed when analyzing time-local master equations.

摘要

在本文中，我们分析了通过记忆核主方程生成的广义泡利信道的经典容量。对于核参数的适当工程设计，具有非局部噪声效应的演化可以产生比纯马尔可夫演化具有更高容量的动力学映射。我们给出了量子比特和量子三态演化的指导性示例。有趣的是，在分析时间局部主方程时未观察到类似行为。
