论文摘要
我们考虑了由Mach-Zhhnder干涉仪引起的光模式和一个可观察的代数，描述了由干涉仪进行的光子数探测器。在物理假设下，我们探讨了这种可观察到的不确定性原理及其在执行类似钟形实验的有用性，以表明对CHSH不平等的侵犯，这是在物理假设下，检测器仅将零与非零数量的光子区分开。我们显示了干涉仪的哪些本地设置导致对CHSH不平等的最大侵犯。
We consider a subgroup of unitary transformations on a mode of light induced by a Mach-Zehnder Interferometer and an algebra of observables describing a photon-number detector proceeded by an interferometer. We explore the uncertainty principles between such observables and their usefulness in performing a Bell-like experiment to show a violation of the CHSH inequality, under physical assumption that the detector distinguishes only zero from non-zero number of photons. We show which local settings of the interferometers lead to a maximal violation of the CHSH inequality.
