摘要：

The coherent-entangled state |alpha, x; lambda > with real parameters lambda is proposed in the two-mode Fock space, which exhibits the properties of both the coherent and entangled states. The completeness relation of |alpha, x; lambda > is proved by virtue of the technique of integral within an ordered product of operators. The corresponding squeezing operator is derived, with its own squeezing properties. Furthermore, generalized P-representation in the coherent-entangled state is constructed. Finally, it is revealed that superposition of the coherent-entangled states may produce the EPR entangled state.
