Token Ring-Shaped Net of Quantum Teleportation byUsing Three-Particle GHZ States

Abstract

Abstract: The authors investigate physical principium for building the quantum teleportation net by using three-particle GHZ states，find out unitary transformation matrix for quantum teleportation of three-particle GHZ states,and design a token ring-shaped quantum teleportation net.The authors propose a scheme for quantum communications net and its protocol.If all stations work as the scheme,quantum communications between any two stations may be realized.All station and manage expense can be monitored by using monitor station.

Key words: quantum communications, quantum teleportation, GHZ states, token ring-shaped net
