An Efficient Multiparty Quantum-State Sharing Scheme

【摘要】 An efficient multiparty quantum secret sharing scheme is proposed,in which the secret is a quantum state,and the dealer encodes the secret by performing the operations of quantum-controlled-not and Hadamard gate.The participants perform the single-particle measurements on their particles,and then can cooperate to recover the original quantum state.In our scheme,both the dealer and the participants do not need to perform the entanglement measurement.Compared with the existing schemes,our scheme is simpler and more efficient.更多还原
