Quantum mechanics allows distribution of intrinsically secure encryption keys by optical
means. Twin-field quantum key distribution is one of the most promising techniques for its …

The Bennett-Brassard 1984 (BB84) protocol is the most widely implemented quantum key
distribution (QKD) scheme. However, despite enormous theoretical and experimental efforts …

Mode-pairing quantum key distribution (MP-QKD) is a potential protocol that is not only
immune to all possible detector side channel attacks, but also breaks the repeaterless rate …

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

Most quantum key distribution schemes exploiting orbital angular momentum-carrying
optical beams are based on conventional set-ups, opening up the possibility of detector side …

Quantum secret sharing (QSS) plays a significant role in multiparty quantum communication
and is a crucial component of future quantum multiparty computing networks. Therefore, it is …

The twin-field class quantum key distribution (TF-class QKD) has experimentally
demonstrated the ability to surpass the fundamental rate-distance limit without requiring a …

Quantum key distribution (QKD) has been experimentally verified over fiber-based link.
However, it still remains problems to be solved. The key rate of QKD protocol naturally …

In this paper, we propose a quantum state recovery scheme based on environment assisted
measurement with weak measurements and flip operations. Before the decoherence …
