Synchronized Bell protocol for detecting non-locality between modes of light
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
