A new Coherent-Entangled state generated by an asymmetric beam splitter and its applications
Abstract
A new kind of tripartite non-symmetric coordinate coherent-entangled state (TNCCES) | β,γ,x > is proposed which exhibits the properties of both coherence and entanglement and makes up a new quantum mechanical representation.We investigate some properties of TNCCES such as completeness and orthogonality which prove it is just a tripartite complete continuous coordinate base. A protocol for generating TNCCES is proposed using asymmetric beam splitter. And in application of TNCCES, we find its corresponding Wigner operator and carry out its marginal distribution form; further a new tripartite entangled squeezed operator is also presented. The multipartite CES and its generation are also disussed.
