论文摘要
在下文中,我们讨论了贝尔协议中两模式光状态中非局部性的检测,其中使用位移算子构建了局部可观察物,该局部可由由强相干态喂养的马赫Zender干涉仪实现。我们报告的数值结果表明,最大化Braunstein-Caves链式钟(BCCB)不平等需要相等的位移阶段。另一方面,我们证明,如果位移的阶段未知,则无法检测到非局部性。因此,必须配备铃铛实验的同步机制。我们讨论了这种机制及其后果。
In the following paper, we discuss a possible detection of non-locality in two-mode light states in the Bell protocol, where the local observables are constructed using displacement operators, implemented by Mach-Zender Interferometers fed by strong coherent states. We report numerical results showing that maximizing the Braunstein-Caves Chained Bell (BCCB) inequalities requires equal phases of displacements. On the other hand, we prove that non-locality cannot be detected if the phases of displacements are unknown. Hence, the Bell experiment has to be equipped with a synchronization mechanism. We discuss such a mechanism and its consequences.
