A Proposal of Teleportation for Three-Particle Entangled State

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.
