Abstract: With GHZ state as a quantum channel,quantum bit secret sharing can be realized after transmitting the information by a classical channel,which is measured by the GHZ state.Based on the above ideas,making full use of  the correlation of a six-particle entanglement GHZ state,by a Bell measurement,four single-particle measurements and the corresponding unitary transformation,a four-qubit secret sharing scheme can be achieved.

Key words: teleportation;GHZ state, secret sharing
