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 read more information leader,in the absence of the establishment of a new quantum channel,can remove some of the participants in the secret reconstruction beer button down shirts for men 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.
