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.

We introduce the so-called coherent-entangled state in the two-mode Fock space; this state exhibits both the properties of the coherent and entangled states. Generalized -representation in the coherent-entangled state is constructed. A protocol for producing the ideal coherent-entangled state is presented. It is shown that the bipartite entangled state can be a superposition of the coherent-entangled states.
