A Novel Scheme for Probabilistic Remote State Preparation Via Partially Four-qubit GHZ States

An efficient proposal for probabilistic remote preparation of single-states is presented by using of four-qubit GHZ states without the introduction of auxiliary particles in this paper. It is noting that this scheme can be utilized to perform the remote state preparation when the information of the partially four-qubit GHZ state is only available for the sender. Some appropriate local unitary operations need to be introduced to improve the successful probability of the preparation, and the total probability is twice as much as the one of the previous proposals. Thus, our scheme can expand the research range of the preparation.
