Abstract:

With a three-particle GHZ entangled state as the quantum channel, a quantum secret sharing scheme is proposed, which realize the unknown three-particle quantum secret sharing, and the safety of the scheme is analyzed. It use the measurement of GHZ state and X-basic on the particles, finally it will realize the three quantum states secret sharing by using the corresponding unitary transformation .Compared with some related literature, the scheme has completed the three-particle quantum secret sharing and not increased the difficulty of making quantum channel, for sharing more particles quantum secret sharing provide the theory evidence.

Key words: quantum optics, three-particle entangled state, quantum state sharing, X-basis measurement, unitary transformation
