论文摘要
量子上下文是量子力学的最困惑和特殊特征之一。简而言之，它指的是量子力学中单个测量结果的结果取决于实际执行的关节测量集。情境性研究在中国科学技术大学（USTC）具有悠久的历史。在这里，我们回顾了过去20年在USTC实现的这一方向的理论和实验进步。我们首先引入著名的与国家无关的上下文性证明。然后，我们提出了一些与光子的量子与非上下文理论的实验测试。最后，我们讨论了关于上下文在一般量子信息科学中的作用及其在量子计算中的应用的研究。
Quantum contextuality is one of the most perplexing and peculiar features of quantum mechanics. Concisely, it refers to the observation that the result of a single measurement in quantum mechanics depends on the set of joint measurements actually performed. The study of contextuality has a long history at University of Science and Technology of China (USTC). Here we review the theoretical and experimental advances in this direction achieved at USTC over the last 20 years. We start by introducing the renowned simplest proof of state-independent contextuality. We then present several experimental tests of quantum versus noncontextual theories with photons. Finally, we discuss the investigation on the role of contextuality in general quantum information science and its application in quantum computation.
