Abstract

We study joint measurability of quantum observables in open systems governed by a master equation of Lindblad form. We briefly review the historical perspective of open systems and conceptual aspects of quantum measurements, focusing subsequently on describing emergent classicality under quantum decoherence. While decoherence in quantum states has been studied extensively in the past, the measurement side is much less understood — here we present and extend some recent results on this topic.

Lindbladian开放量子系统的联合可测量性

研究了由Lindblad形式的主方程控制的开放系统中量子可观测量的联合可测性。我们简要回顾了开放系统的历史观点和量子测量的概念方面，随后重点描述了量子退相干下的涌现经典性。虽然过去已经对量子态的退相干进行了广泛的研究，但测量方面的理解却少得多-在这里，我们提出并扩展了有关该主题的一些最新结果。

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.
