Coherent-Entangled State in Three-Mode and Its Applications

Abstract

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.

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

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

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.

NEW THREE-MODE COHERENT-ENTANGLED STATE DERIVED BY VIRTUE OF DECOMPOSING NORMALLY ORDERED GAUSSIAN OPERATOR INTEGRAND

Gang Ren, Hong-Yi Fan

We introduce a new kind of three-mode coherent-entangled state (CES) |x,β1,β2〉, which has both properties of the coherent state and the entangled state. We derive it by virtue of decomposing normally ordered Gaussian operator integrand. An experiment setup to produce the ideal coherent-entangled state is presented. The corresponding Wigner operator and squeezing operator in terms of CES are also given.

THE APPLICATION AND CHARACTERISTICS OF THE COHERENT ENTANGLED STATE |β, x〉

The coherent entangled state |β, x〉 is proposed in Fock space, which exhibits both the properties of the coherent and entangled states. The |β, x〉 makes up a new quantum mechanical representation, and the completeness relation of |β, x〉 is proved by virtue of the technique of integral within an ordered product of operators. The corresponding Schmidt decomposition of |β, x〉 is investigated. Furthermore, a feasible experimental scheme of |β, x〉 is presented, and generalized P-representation is constructed in the coherent entangled state |β, x〉.

Quadrature-amplitude measurement for new tripartite coherent entangled state and its teleportation

Hong-Yi Fan, Liyun Hu, Wen-Qin Wang

A new kind of three-mode coherent entangled state (CES) |β,γ,x⟩ is proposed, which possesses the properties of both a coherent state and an entangled state. |β,γ,x⟩ makes up a new quantum mechanical representation. Remarkably, quadrature-amplitude measurement for |β,γ,x⟩ leads to its collapse to the two-mode CES. A teleportation protocol of |β,γ,x⟩ is proposed by employing the Schmidt decompositions of both |β,γ,x⟩ and the bipartite entangled state |η⟩.

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.
