Generation of a new bipartite coherent-entangled state and its applications

doi:10.1088/1674-1056/21/3/030304

Abstract A new bipartite coherent-entangled state is introduced in the two-mode Fock space, which exhibits the properties of both a coherent state and an entangled state. The set of coherent-entangled states makes up a complete and partly nonorthogonal representation. A simple experimental scheme to produce the coherent-entangled state using an asymmetric beamsplitter is proposed. Some applications of the coherent-entangled state in quantum optics are also presented.

Keywords: bipartite coherent-entangled state asymmetric beamsplitter Einstein-Podolsky-Rosen entangled state squeezed state
