<p>Addressing the problems where existing quantum secret sharing protocols rely on entanglement resources and lack perfect verification mechanisms, this paper proposes a verifiable dynamic multi-party quantum secret sharing protocol based on orthogonal product states. This scheme uses locally indistinguishable orthogonal product states as information carriers, effectively eliminating the dependence on entangled states. The protocol constructs a dual verification mechanism integrating identity legitimacy authentication and secret integrity verification, and supports the flexible dynamic addition and deletion of members. Simulation experiments based on the IBM Qiskit platform and security analysis show that the protocol can effectively resist various malicious attacks, verifying the correctness of the scheme, and providing an effective pathway for building low-cost, highly flexible quantum communication networks.</p>
