Abstract

A quantum teleportation scheme to teleport a kind of tripartite entangled states of continuous variables by using a quantum channel composed of three bipartite entangled states is proposed.The joint Bell measurement is feasible because the bipartite entangled states are complete and the squeezed state has a natural representation in the entangled state basis.The calculation is greatly simplified by using the Schmidt decomposition of the entangled states.

Application of three-mode Einstein-Podolsky-Rosen entangled state with continuous variables to teleportation

Liyun Hu, Lu Hai-Liang

We consider how to teleport two- and three-mode Einstein–Podolsky–Rosen entangled states (|η⟩ and | p t , χ 2 , χ 3 ⟩) via a | p t ,χ 2 ,χ 3 ⟩ quantum channel for continuous variables. Using the complete and orthogonal representation of the entangled states, we can not only find the a complete basis set for the joint measurement but also propose the specific scheme of teleportation. Our calculation can be greatly simplified by using their Schmidt decompositions.

Application of Bipartite and Tripartite Entangled State Representations in Quantum Teleportation of Continuous Variables

Hong‐Chun Yuan, Qi Kai-Guo

We mostly investigate two schemes. One is to teleport a multi-mode W-type entangled coherent state using a peculiar bipartite entangled state as the quantum channel different from other proposals. Based on our formalism, teleporting multi-mode coherent state or squeezed state is also possible. Another is that the tripartite entangled state is used as the quantum channel of controlled teleportation of an arbitrary and unknown continuous variable in the case of three participators.

Quantum teleportation of an entangled pair for continuous variables

В. Н. Горбачев, A. I. Zhiliba, Andrew I. Trubilko

The teleportation of a two-particle entangled state, using a Greenberger-Horne-Zeilinger triplet, for continuous variables is studied. The basis for joint three-particle measurements is found, where the vectors describe the states in which only two of three particles are entangled. It represents the measurement of the momentum of one particle and the difference of coordinates and the sum of momenta of the two other particles. An optical realization of this scheme is presented, which uses squeezed states of light and reduces the measurement of momentum and coordinate to the detection of quadrature operators of the electromagnetic field.

Continuous-Variable Quantum Teleportation of Entangled Coherent States

Sun Yong, Man Zhong-Xiao, Yun‐Jie Xia

We propose a quantum teleportation scheme for tripartite entangled coherent state (ECS) with continuous variable. Our scheme is feasible and economical in the sense that we need only linear optical devices such as beam splitters, phase shifters and photon detectors and employ three bipartite maximally ECSs as quantum channels. We also generalize the tripartite scheme into multipartite case and calculate the minimum average fidelity for the schemes in tripartite and multipartite cases.
