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

A scheme of teleportation of a N-particle entangled GHZ state through a two-paticle entangled quantum channel was proposed.Firstly,the maximally entangled states were 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.Compared with other schemes,this scheme saves the quantum entanglement channel resources.
