Remote Preparation of Three-Particle GHZ Class States

We propose a remote state preparation (RSP) scheme of three-particle Greenberger-Horne-Zeilinger (GHZ)class states,where quantum channels are composed of two maximally entangled states.With the aid of forward classicalbits,the preparation of the original state can be successfully realized with the probability 1/2,the necessary classicalcommunication cost is 0.5 bit on average.If the state to be prepared belongs to some special states,the success probabilityof preparation can achieve 1 after consuming one extra bit on average.We then generalize this scheme to the case thatthe quantum channels consist of two non-maximally entangled states.
