Some applications of a new coherent-entangled state in two-mode Fock space

Abstract

Using the technique of integration within an ordered product of operators, we find a new kind of coherent-entangled state (CES), which exhibits both coherent and entangled state properties. The set of CESs makes up a complete and partly nonorthogonal representation. Using a beam splitter, we propose a simple experimental scheme to produce the CES. Finally, we present some applications of CESs in quantum optics.

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.

Generation of a new bipartite coherent-entangled state and its applications

Bao-Lai Zhang, Xiang‐Guo Meng, Ji‐Suo Wang

A new bipartite coherent-entangled state is introduced in the two-mode Fock space, which exhibits the properties of both a coherent state and an entangled state. The set of coherent-entangled states makes up a complete and partly nonorthogonal representation. A simple experimental scheme to produce the coherent-entangled state using an asymmetric beamsplitter is proposed. Some applications of the coherent-entangled state in quantum optics are also presented.

Multi-mode Coherent-Entangled State Representation and Its Applications

Heng-Mei Li, Yuan Hong-Chun

We introduce the so-called coherent-entangled state (CES) in the four-mode Fock space, which makes up a new quantum mechanical representation owing to completeness relation and orthogonal property. Its standard Schmidt decomposition and experimental generation using beam-splitter (BS) are proposed. In addition, its applications in quantum optics are presented. Finally, we extend it to multi-mode case and discuss some applications, too.

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.

Four-mode coherent-entangled state and its application

Hongqi Li, Ting-Qi Ren, Yunhai Zhang +1 more

A new kind of four-mode continuous variable coherent-entangled state is proposed in the Fock space by using the technique of integration within an ordered product, which exhibits both the properties of a coherent state and an entangled state, and spans a complete and orthonormal representation. The conjugate state of the four-mode continuous variable coherent-entangled state is derived by using the Fourier transformation. Moreover, a simple experimental protocol of generating a four-mode continuous variable coherent-entangled state is proposed by using beam splitters. As applications of this four-mode continuous variable coherent-entangled state, a four-mode entangled state and a four-mode squeezing-Fresnel operator are constructed.

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.
