Quantum communication networks are crucial for both secure communication and
cryptographic networked tasks. Building quantum communication networks in a scalable …

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 …

This article considered deficiencies of the flourishing blockchain technology manifested by
the development of quantum computation. We show that the future blockchain technology …

Quantum Byzantine fault tolerance (BFT) consensus is a secure and reliable mechanism
that enables network nodes to reach an agreement even in the presence of faulty nodes, by …

Byzantine agreement, the underlying core of blockchain, aims to make every node in a
decentralized network reach consensus. Classical Byzantine agreements unavoidably face …

We introduce a new quantum protocol for solving detectable Byzantine agreement (also
called detectable broadcast) between three parties, and also for solving the detectable liar …

In this paper, we propose a protocol of quantum communication to achieve Byzantine
agreement among multiple parties. Our protocol's striking feature compared to the existing …

Blockchain has revolutionized many fields, such as distributed sensor networks, finance,
and cryptocurrency. Consensus between distributed network nodes is at the core of such …

Due to its fundamental principles, quantum theory holds the promise to enhance the security
of modern cryptography, from message encryption to anonymous communication, digital …

Clock synchronization for nonfaulty processes in multiprocess networks is indispensable for
a variety of technologies. A reliable system must be able to resynchronize the nonfaulty …
