Abstract

We introduce a new entangled state composed of Fock states, a coherent state and a single-photon-added state. The nonclassical properties are demonstrated by phase squeezing, photon-number squeezing (sub-Poisson statistics), the violation of Cauchy-Schwarz inequality, and the negativity of Wigner function of the proposed entangled state.
