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 …

Abstract Device-independent (DI) protocols, such as DI conference key agreement (DICKA)
and DI randomness expansion (DIRE), certify private randomness by observing nonlocal …

Multipartite entanglement enables secure and anonymous key exchange between multiple
parties in a network. Greenberger-Horne-Zeilinger states have been introduced as resource …

In the field of post-quantum security, isogeny-based cryptography stands out for its ability to
fight quantum attacks. One of the key operations in isogeny-based schemes is finite field …

Sharing multi-partite quantum entanglement between parties allows for diverse secure
communication tasks to be performed. Among them, conference key agreement (CKA)-an …

Among the many applications of quantum information processes, one of the most mature
both from a theoretical and practical point of view is undoubtedly Quantum Key Distribution …

Quantum conference key agreement (QCKA) generalises the traditional two-party quantum
key distribution (QKD) paradigm to multiple users, enabling them to share a common …
