Experimental fully contextual correlations

摘要:

量子关联是有背景的,但一般来说,没有什么能阻止更多的有背景的关联的存在。我们确定并测试了一个非上下文不等式,其中量子违反不能通过任何假设的后量子理论来改善,并使用它来实验获得非上下文相关的分数小于0.06的相关性。我们的相关性是实验产生的顺序兼容测试的结果编码在一个四态量子系统的偏振和路径的一个单光子。

英文摘要:

Quantum correlations are contextual yet, in general, nothing prevents the existence of even more contextual correlations. We identify and test a noncontextuality inequality in which the quantum violation cannot be improved by any hypothetical postquantum theory, and use it to experimentally obtain correlations in which the fraction of noncontextual correlations is less than 0.06. Our correlations are experimentally generated from the results of sequential compatible tests on a four-state quantum system encoded in the polarization and path of a single photon.
