论文摘要
最近，基于信息理论距离的方法，已得出了非上下文隐藏可变量模型的不平等，并违反了四级系统的所有状态的量子力学。在这项工作中，我们在实验上证明了单个光子违反了这种不平等。我们的实验提供了一种从信息理论的角度研究量子和经典相关性区别的方法。
Recently, an inequality satisfied by non-contextual hidden-variable models and violated by quantum mechanics for all states of a four-level system has been derived based on information-theoretic distance approach to non-classical correlations. In this work, we experimentally demonstrate violation of this inequality with single photons. Our experiment offers a method to study a distinction between quantum and classical correlations from an information-theoretic perspective.
