Abstract

A quantum secret sharing scheme is proposed by making use ofquantum registers. In the proposed scheme, secret message state isencoded into multipartite entangled states. Several identicalmulti-particle entanglement states are generated and each particleof the entanglement state is filled in different quantum registerswhich act as shares of the secret message. Two modes, i.e. thedetecting mode and the message mode, are employed so that theeavesdropping can be detected easily and the secret message may berecovered. The security analysis shows that the proposed scheme issecure against eavesdropping of eavesdropper and cheating ofparticipants.
