标题： Quantum contextuality for a three-level system sans realist model

摘要： 最近，一种有趣的非经典效应被提出，可以视为量子力学中的上下文性的一种形式，并通过区分测量单个可观测值的不同路径，在四能级系统中得到了演示。 在本文中，我们为单个三重态提供了一个更简单的证明版本，该证明也处于量子力学的形式体系内，并且不依赖于任何实在论的隐变量模型。 本证明中，本征值的简并性和L$\ddot{u}$投影规则起到了重要作用。 显示英文摘要

摘要： Recently, an interesting form of non-classical effect which can be considered as a form of contextuality within quantum mechanics, has been demonstrated for a four-level system by discriminating the different routes that are taken for measuring a single observable. In this paper, we provide a simpler version of that proof for a single qutrit, which is also within the formalism of quantum mechanics and without recourse to any realist hidden variable model. The degeneracy of the eigenvalues and the L$\ddot{u}$der projection rule play important role in our proof.
