Quantum secret sharing (QSS) is one important branch of quantum cryptography.Based on the studies of multi-shared quantum bits,a new dynamic quantum bit sharing protocol was proposed.The participation of the shared members is hierarchical in this protocol.The quantum information leader,in the absence of the establishment of a new quantum channel,can remove some of the participants in the secret reconstruction system.After the layoffs,the leader can also update the quantum information using quantum operations,and the remaining effective partici-pants can recover the new quantum information without performing additional operations.In addition,the correct-ness,security and the hierarchy of the participants of the protocol were discussed.
