Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

During the past decade the interaction of light with multiatom ensembles has attracted much
attention as a basic building block for quantum information processing and quantum state …

Following some ideas of the quantum secret sharing (QSS) protocol (2008, Phys. Lett. A
372, 1957), we propose an efficient quantum private comparison (QPC) protocol for …

The central theme of this paper is that we propose an efficient protocol for comparing the
equal information with the help of a third party (TP). We assume that TP is semi-honest, ie …

Based on EPR pairs, this paper proposes a different quantum private comparison (QPC)
protocol enabling two parties to compare the equality of their information without revealing …

We describe quantum protocols for voting and surveying. A key feature of our schemes is the
use of entangled states to ensure that the votes are anonymous and to allow the votes to be …

This paper proposes a simple voting protocol based on Quantum Blockchain. Despite its
simplicity, our protocol satisfies the most important properties of secure voting protocols: is …

Anonymity in networked communication is vital for many privacy-preserving tasks. Secure
key distribution alone is insufficient for high-security communications. Often, knowing who …

Distributing entanglement among multiple users is a fundamental problem in quantum
networks, requiring an efficient solution. In this work, a protocol is proposed for extracting …

This paper proposes a pioneering quantum private comparison (QPC) protocol for n users.
State-of-the-art QPC protocols have been designed for two users who wish to compare their …
