Quantum Multi-Party Threshold Private Set Intersection with Explicit Cardinality Testing
Zixian Gong, Kun Tian, Yi Zhang +1
Threshold private set intersection (TPSI) allows parties to reveal their intersection only when its cardinality reaches a prescribed threshold. Existing quantum TPSI protocols typi…

Zixian Gong, Kun Tian, Yi Zhang +1
Threshold private set intersection (TPSI) allows parties to reveal their intersection only when its cardinality reaches a prescribed threshold. Existing quantum TPSI protocols typi…
Authenticated Private Set Intersection: A Merkle Tree-Based Approach for Enhancing Data Integrity
Zixian Gong, Zhiyong Zheng, Zhe Hu +4
Private Set Intersection (PSI) enables secure computation of set intersections while preserving participant privacy, standard PSI existing protocols remain vulnerable to data integ…
Authenticated Sublinear Quantum Private Information Retrieval
Fengxia Liu, Zhiyong Zheng, Kun Tian +5
This paper introduces a novel lower bound on communication complexity using quantum relative entropy and mutual information, refining previous classical entropy-based results. By l…
