Bell nonlocality tests with asymmetric entangled coherent states

C Park (Seoul National University)

Bell nonlocality test using an asymmetric form of two-mode entangled coherent state (ECS) where 
the two local amplitudes have different values is studied. It is shown that asymmetric ECSs are useful
 for nonlocality tests with obvious advantages over the symmetric form of ECSs when assuming the
 same resource requirements. The effect of asymmetric decoherence settings and detection
 inefficiency in Bell nonlcality tests are also discussed.
