This research advances practical Quantum Secret Sharing by introducing a detection mechanism for intermediate sets that mitigate information leakage in ramp protocols. By optimizing reconstruction communication costs relative to the number of parties, the scheme addresses critical efficiency bottlenecks currently limiting deployment on general quantum networks. The work represents a significant step toward balancing robust security with scalable resource usage in emerging distributed quantum architectures.
Shaanxi Normal University’s Quantum QSS Scheme Features Leakage Control

Researchers at Shaanxi Normal University developed a new quantum secret sharing scheme, addressing leakage risks in ramp schemes and boosting efficiency.
Researchers at Shaanxi Normal University in Xi’an have developed a new quantum secret sharing scheme designed to address a critical vulnerability in existing protocols: information leakage from participants. The team affiliated with the School of Mathematics and Statistics presents a method for detecting intermediate sets, groups capable of partially revealing a secret without full reconstruction, and a scheme incorporating this detection capability. This work focuses on sharing quantum secrets and analyzes…
