It is a fundamental problem in physics of what principle limits the correlations as predicted by our current description of nature, based on quantum mechanics. One possible explanation is the "global exclusivity" principle recently discussed in Phys. Rev. Lett. 110, 060402 (2013). In this work we show that this principle actually has a much stronger restriction on the probability distribution. We provide a tight constraint inequality imposed by this principle and prove that this principle singles out quantum correlations in scenarios represented by any graph. Our result implies that the exclusivity principle might be one of the fundamental principles of nature.
这是物理学中的一个基本问题，即基于量子力学的我们当前对自然界的描述所预测的关联受到什么原理的限制。一种可能的解释是最近在《物理评论快报》110，060402（2013）中讨论的“全局排他性”原理。在这项工作中，我们表明这个原理实际上对概率分布有更强的限制。我们提供了这个原理施加的一个严格的约束不等式，并证明这个原理在任何图表示的场景中都能挑出量子关联。我们的结果表明，排他性原理可能是自然界的基本原理之一。
