Multiparty remote state preparation (MRSP) is a procedure for multiparty collaboration with each other for remote preparation of a known quantum state to a distant party. We show that it is possible to achieve a unity fidelity remote preparation of the state by properly choosing the measurement basis. This protocol may be used for converging the split information at one point.
