Remote State Preparation (RSP) is a branch of quantum information processing. In order to prepare the same state to multiple recipients, a broadcast-based RSP protocol was proposed for one sender and two receivers, and then it was extend to N receivers. GHZ states were used as shared quantum resources. By constructing two special measurement bases, the sender realized two times of multi-particle projective measurement; then the receivers used unitary operation to recover the prepared state depending on the measurement results. Analysis shows that multiparty RSP protocol can be used to broadcast information in quantum network.
