A New Tripartite Coherent-Entangled State Generated by An Asymmetric Beam-Splitter and Its Applications

Abstract

A new kind of tripartite coherent-entangled state (CES) ${|\beta ,\gamma ,x⟩}_{\mu \nu \tau }$ is proposed, which exhibits the properties of both coherence and entanglement. We investigate its completeness and orthogonality, and find it can make up a representation of tripartite CES. A protocol for generating the tripartite CES is proposed using asymmetric beam splitter. Applications of the tripartite CES in quantum optics are also presented.
