Abstract

A new kind of bipartite coherent–entangled state (CES) is introduced which exhibits both coherent state and entangled state properties. A protocol of generating such a CES is proposed using an asymmetric beamsplitter. It is shown that the bipartite EPR entangled state can be a superposition of the CESs. Applications of CESs in quantum optics are also presented.

The construction, properties and applications of a new bipartite coherent-entangled state in the two-mode Fock space

Xiang‐Guo Meng, Ji‐Suo Wang, Bao‐Long Liang

Using the technique of integration within an ordered product (IWOP) of operators, we find a new kind of bipartite coherent-entangled state (CES) that exhibits both coherent state and entangled state properties. The set of CESs makes up a complete and partly nonorthogonal representation. Using an asymmetric beamsplitter we propose a simple experimental scheme for producing the CES. Finally, we present some new quantum states related to the CES and some applications of the CES to quantum optics.

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

Xu Ma, Shuang-Xi, Zhang, Chuanfei Dong

A new kind of tripartite coherent-entangled state (CES) $\ket{β,γ, x}_{μντ}$ 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.

A new Coherent-Entangled state generated by an asymmetric beam splitter and its applications

Xu Ma, Shuangxi Zhang, Gang Ren

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.

Coherent-Entangled State in Three-Mode and Its Applications

Fan Hong‐Yi, Wen-Qin Wang

We introduce the new concept of coherent-entangled state (CES). By virtue of the technique of integration within an ordered product of operators we introduce a new kind of three-mode CES |β,γ, x ⟩, which exhibits both properties of the coherent state and the entangled state. |β,γ, x ⟩ makes up a new quantum mechancial representation. Its applications in quantum optics are also presented.
