Teleportation of a N-particle entangled GHZ sate via  two-particle entangled quantum channel

Abstract

Abstract:

A scheme of teleportation of a N-particle entangled GHZ state through a two-paticle entangled quantum channels was proposed. Firstly, the maximally entangled states was taken as quantum channels, then, the case of nonmaximally entangled channels was considered. It was found that by implementing H transformation and von Neumann measurement, introducing an ancilly qubit, when the channels are nonmaxially entangled states, constructing an unitary transformation properly, teleportation of three-paticle entangled GHZ state cound be implemented with certain probability, finally, the N-particle entangled GHZ state was discussed. Compare with other schemes,this scheme saves the quantum entanglement channel resources.

Key words: teleportation, three-paticle entangled state, entangled GHZ state, nonmaximally entangled quantum channels
