摘要：
Based on the entanglement swapping of EPR pairs, a dynamic quantum secret sharing (QSS) scheme is proposed. The scheme has the following dynamic properties. Without modifying the secret shares of old agents, (1) an agent can join or leave the QSS; (2) two QSSs (m parties in the first QSS and n parties in the second QSS) can be integrated into an (m + n)-party QSS. Compared with the existing QSS schemes, the proposed dynamic QSS is more flexible in practical applications.
