论文摘要
上下文性提供了量子现象的基本特征之一，可以用作大量量子信息处理中的资源。在本文中，我们总结并得出了一些基于Greenberger-Horne-Zeilinger态的Kochen-Specker定理的不同的非上下文模型的同等非上下文不等式。这些非上下文不等式等于某些相关项目，这些相关项目既适用于非秘密隐藏变量理论和量子力学。因此，我们使用由旋转，路径和轨道角动量编码的单光孔高座状格林伯格 - 泽林格状态，我们通过测试Kochen-Specker定理的几种依赖状态依赖性的非上下文模型，通过测试一种极端最简单的MERMERMIN类似于Mermin类似的平等。
Contextuality provides one of the fundamental characterizations of quantum phenomena, and can be used as a resource in lots of quantum information processing. In this paper, we summarize and derive some equivalent noncontextual inequalities from different noncontextual models of the proofs for Kochen-Specker theorem based on Greenberger-Horne-Zeilinger states. These noncontextual inequalities are equivalent up to some correlation items which hold both for noncontextual hidden variable theories and quantum mechanics. Therefore, using single-photon hyperentangled Greenberger-Horne-Zeilinger states encoded by spin, path and orbital angular momentum, we experimentally verify several state-dependent noncontextual models of the proofs for the Kochen-Specker theorem by testing an extreme simplest Mermin-like inequality.
