摘      要：I present a new scheme for probabilistic remote preparation of a general two-qubit state from a sender to either of two *** quantum channel is composed of a partial entangled tripartite Greenberger-Horne-Zeilinger (GHZ) state and a W-type state.I try to realize the remote two-qubit preparation by using the usual projective measurement and the method of positive operator-valued measure,*** corresponding success probabilities of the scheme with different methods as well as the total classical communication cost required in this scheme are also calculated.
