摘要
We present a scheme for probabilistic remote preparation of multi-qubit with three-party from a sender toeither of two receivers.The quantum channel is composed of a partial entangled tripartite GHZ state.We obtain thesuccessful total probability of the scheme in the general case and special case,respectively.We also calculate total classicalcommunication cost required in the RSP process with three-party in the general case and special case,respectively.
We present a scheme for probabilistic remote preparation of multi-qubit with three-party from a sender to either of two receivers. The quantum channel is composed of a partial entangled tripartite GHZ state. We obtain the successful totM probability of the scheme in the general case and special case, respectively. We also calculate total classical communication cost required in the RSP process with three-party in the general case and special case, respectively.
