摘要：
本文定义了一种操作性（基于测量）方案，用于关联开放量子系统中的测量侵入性与非经典记忆效应的存在。其理论基础是：当相应可观测量与系统密度矩阵在同一基下对角化时，（无记忆）量子马尔可夫动力学具有非侵入可测性；而违背该性质可关联到本征非经典记忆效应。从这一视角，可推导出量子记忆效应导致Leggett-Garg不等式违背的相关条件。该方法适用于开放量子动力学，包括由完全幺正（微观）描述、随机哈密顿动力学导出的时间演化，以及广泛的非幺正系统-环境模型（ bipartite Lindblad方程）。
英文摘要：
An operational (measurement based) scheme that connects measurement invasiveness and the presence of non-classical memory effects in open quantum systems is defined. Its underlying theoretical basis relies on a non-invasive measurability of (memoryless) quantum Markovian dynamics when the corresponding observable is diagonal in the same basis as the system density matrix. In contrast, violation of this property can be related to intrinsic non-classical memory effects. Related conditions for violation of Leggett-Garg inequality due to quantum memory effects emerge from this perspective. The developed approach applies to open quantum dynamics whose time-evolution is derived from a full unitary (microscopic) description, stochastic Hamiltonian dynamics, as well as for a broad class of non-unitary system-environment models (bipartite Lindblad equations).
