    Based on the non-locality entanglement correlation of W state, a quantum secret sharing protocol was proposed by utilizing quantum teleportation. In the proposed protocol, Alice prepares a three-particle W state, and sends any two-particle of the W state to Bob1 and Bob2, respectively, then performs Bell bases joint measurement on her own particles. According to Alice’s measurement result, Bob1 and Bob2 can jointly obtain the secret information by performing corresponding local operations. The security of the proposed protocol was analyzed in detail. It is shown that the proposed protocol can resist several attacks, such as intercept-resend attack, entanglement-and-measure attack, and etc.
