Quantum teleportation of an entangled pair for continuous variables

Abstract

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.

Teleportation of entanglement for continuous variables

В. Н. Горбачев, Andrew I. Trubilko

Teleportation of a pure two particle entangled state of continuous variables by triplet of the Greenberger-Horne-Zeilinger form is considered. The three-particle basis needed for a joint measurement is found. It describes a measurement of momentum one of single particle and total moment and relative position of the two others. Optical realization using squeezed state of the light is discussed.

Teleportation of entangled states

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

Teleportation of some pure entangled states of discrete and continuous variables is considered using a multi-particle quantum channel; particularly a Greenberger-Horne-Zeilinger channel. Both the protocols we have found for the discrete and continuous versions have identical features due to the properties of the quantum channel. In this way some entangled states can be teleported perfectly; a non-Bell-state measurement is needed in contrast to the one-by-one protocol where an unknown state can be recovered by all receivers only. For teleportation of continuous variables an optical implementation using squeezed light states is discussed.

A Proposal of Teleportation for Three-Particle Entangled State

Chui‐Ping Yang, Guang‐Can Guo

We propose a scheme for teleporting a three-particle entangled Greenberger-Horne-Zeilinger state to three distant users. The scheme operates essentially through the sharing of Einstein-Podolsky-Rosen pairs followed by only local measurements and unitary operations. It can be regarded as a method for generating the entanglement of particles distributed in a communication network.
