Summary

This paper addresses challenges in quantum secret sharing under non-maximal quantum access structures (QAS), specifically focusing on a structure called "hyperstar with three hyperedges." The authors characterize forbidden and intermediate sets within this QAS, define a representative element QAS as a substructure, and propose a universal, efficient, and perfect quantum secret sharing scheme. By using lightweight quantum resources and leveraging classical secret sharing as an auxiliary, the scheme reduces quantum state preparation difficulty, improves security, and enhances resource utilization efficiency.
