Quantum Protocol for Secure Multiparty Logical AND With Application to Multiparty Private Set Intersection Cardinality

Run-Hua Shi et al.

Summary: In this paper, the importance of logical AND in scientific computing is discussed. A new privacy-preserving problem is defined and a novel quantum protocol is proposed to address this problem. The proposed protocol ensures information-theoretical security and reduces the communicational complexity. Additionally, an application of the protocol is investigated and a feasible quantum protocol for private set intersection cardinality is designed based on the improved quantum protocol.

A cost-effective quantum protocol for secure multi-party multiplication

Kartick Sutradhar et al.

Summary: This paper proposes a secure multi-party quantum multiplication protocol based on the (t, n) threshold approach, where t out of n participants can efficiently execute it. The protocol is more cost-effective and secure compared to existing protocols, as secrets are shared among players using secret sharing.
