| 摘 要： | 提出了使用GHZ的三粒子纠缠态作为量子信道来实现三个未知量子纠缠态的秘密共享，并对方案的安全性进行了证明。该方案通过对粒子进行三粒子GHZ态的测量和X基测量，最后使用相应的幺正变换来实现三个量子位的秘密共享。与相关文献相比，此方案既完成了对未知三粒子纠缠态的秘密共享又没有增加量子信道的实现难度，为共享更多位的量子秘密共享方案提供了理论依据。

| 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. |

| Keywords: | quantum optics three-particle entangled state quantum state sharing X-basis measurement unitary transformation |
