| 摘 要： | 提出了一种基于连续变量压缩态的多方对多方的量子秘密共享协议．该协议中,Alice集团中的成员将要共享的秘密信息直接编码在由Bob集团制备的量子态上．两个集团Alice和Bob共享一组经典秘密,当且仅当Alice或者Bob集团中的所有成员共同参与,才能恢复出秘密,任何部分成员都不能恢复出秘密信息该方案与基于单光子实现的方案相比,效率更高,实现更加简单．分析表明该协议是安全的．

| Abstract: | A quantum secret sharing protocol between multiparty and multiparty based on squeezed state is proposed. In the protocol, the members in the Alice group code the secret information on the quantum states prepared by the members in the Bob group. The groups Alice and Bob share a classical secret. The secret could be reconstructed if and only if all the members of the group Alice or the group Bob collaborate, any part of each group can＇t reconstruct the secret. Compared with the protocols based on single photon, this protocol is more efficient and realized more simply. The analysis shows that the protocol is secure. |
