Abstract
Passing a photon number state through a balanced beam splitter will produce an entangled state in which the phases of the two output modes are highly correlated. We show that Bell’s inequality can be violated using this entangled state and two distant interferometers. The output modes of the beam splitter can be viewed as a generalized form of an entangled Schrodinger cat state, which may have practical applications in quantum communications.
