Coherent-one-way (COW) quantum key distribution (QKD) is a significant communication
protocol that has been implemented experimentally and deployed in practical products due …

The large-scale deployment of quantum secret sharing (QSS) in quantum networks is
currently challenging due to the requirements for the generation and distribution of …

As quantum theory allows for information processing and computing tasks that otherwise are
not possible with classical systems, there is a need and use of quantum Internet beyond …

Quantum conferencing enables multiple nodes within a quantum network to share a secure
conference key for private message broadcasting. The key rate, however, is limited by the …

Twin-field quantum key distribution (TFQKD) enables two distant parties to establish a
shared secret key, by interfering weak coherent pulses (WCPs) in an intermediate …

This paper presents a new quantum protocol designed to transmit information from one
source to many recipients simultaneously. The proposed protocol, which is based on the …

A quantum conference key agreement (QCKA) protocol based on differential-phase-shift
quantum key distribution is presented, which provides a common secret key for secure …

In response to the emerging security challenges brought about by advances in quantum
technology, traditional key agreement methods are encountering vulnerabilities. To address …

Quantum correlation is a key resource for a variety of quantum information processing and
communication tasks, the efficient utilization of which has been a longstanding concern, and …

In this paper, on the design process of a multiparty quantum key agreement protocol within
ad d‐dimensional Hilbert space is elaborated upon. A circular‐type multiparty quantum key …
