论文摘要
量子力学中非上下文性的两个不同且逻辑上独立的概念。首先，如果每个Ontic（隐藏）状态确定每个测量结果的概率，则称为量子力学的本体论（隐藏变量）模型，称为非秘密，独立于同时执行其他测量值的结果。其次，如果任何两个由相同的自动接合操作员代表的两个测量值或等效地，则本体模型是非副本，它们在每个量子状态下具有相同的结果概率分布，也具有相同的概率分布在每个Ontic状态下的结果。我将同时称为第一个概念，即第二个测量非上下文性。在本文中，我将概述并批判性地分析文献中一些最重要的上下文叙述，并将其集成在这两个类别之下。
There are two different and logically independent concepts of noncontextuality in quantum mechanics. First, an ontological (hidden variable) model for quantum mechanics is called noncontextual if every ontic (hidden) state determines the probability of the outcomes of every measurement independently of what other measurements are simultaneously performed. Second, an ontological model is noncontextual if any two measurements which are represented by the same self-adjoint operator or, equivalently, which have the same probability distribution of outcomes in every quantum state also have the same probability distribution of outcomes in every ontic state. I will call the first concept simultaneous noncontextuality, the second measurement noncontextuality. In the paper I will overview and critically analyze some of the most significant accounts of contextuality in the literature and subsume them under these two categories.
