    Abstract

    Two schemes for quantum secret sharing of single-qubit state were proposed. A symmetric three-qubit entangled state and an asymmetric three-qubit entangled state were used as quantum channel, respectively. The sender performs Bell-basis measurements on her particles, and the cooperator operates single-particle measurements on his particles, then the state receiver can reconstruct the original state by applying the appropriate unitary operation. The schemes can also be generalized to the case of arbitrary two-qubit and multi-particle entangled state. The security against certain eavesdropping attacks is also considered. These protocols are considered to be secure.
