Three-party, four-party quantum secret sharing schemes are proposed based on two different four-particle entangled states, in which the secret information adopted is an identical unknown two-particle entangled state. In the quantum secret sharing scheme, the sender implements appropriate Bell or GHZ state measurement on the owned particles. The sender and partner inform the receiver measurement results by classical communications. The receiver can reconstruct the initial quantum state information by implementing the corresponding quantum operation with the assistance of other collaborators. The security of the proposed two schemes are discussed and compared, and it’s found that the four-party quantum secret sharing sche me is more reliable.
