Fast single-photon detectors and real-time key distillation enable high secret-key-rate quantum key distribution systems [PDF]
Nature Photonics, 2022 Quantum key distribution has emerged as the most viable scheme to guarantee information security in the presence of large-scale quantum computers and, thanks to the continuous progress made in the past 20 years, it is now commercially available. However,

Measurement-device-independent quantum key distribution. [PDF]
Physical Review Letters, 2011 How to remove detector side channel attacks has been a notoriously hard problem in quantum cryptography. Here, we propose a simple solution to this problem--measurement-device-independent quantum key distribution (QKD).

SECURITY OF QUANTUM KEY DISTRIBUTION [PDF]
International Journal of Quantum Information, 2008 Quantum Information Theory is an area of physics which studies both fundamental and applied issues in quantum mechanics from an information-theoretical viewpoint. The underlying techniques are, however, often restricted to the analysis of systems which satisfy a certain independence condition.

Quantum dense key distribution [PDF]
Physical Review A, 2004 This paper proposes a new protocol for quantum dense key distribution. This protocol embeds the benefits of a quantum dense coding and a quantum key distribution and is able to generate shared secret keys four times more efficiently than BB84 one. We hereinafter prove the security of this scheme against individual eavesdropping attacks, and we present ...

Quantum Key Distribution Using Quantum Faraday Rotators [PDF]
, 2007 We propose a new quantum key distribution (QKD) protocol based on the fully quantum mechanical states of the Faraday rotators. The protocol is unconditionally secure against collective attacks for multi-photon source up to two photons on a noisy ...

Twin-field quantum key distribution over a 511 km optical fibre linking two distant metropolitan areas [PDF]
Nature Photonics, 2021 The basic principle of quantum mechanics1 guarantees the unconditional security of quantum key distribution (QKD)2–6 at the cost of forbidding the amplification of a quantum state.

Twin-field quantum key distribution without optical frequency dissemination [PDF]
Nature Communications, 2022 Twin-field (TF) quantum key distribution (QKD) has rapidly risen as the most viable solution to long-distance secure fibre communication thanks to its fundamentally repeater-like rate-loss scaling.

On the Security of Quantum Key Distribution Networks ⋆
Cryptography, 2023 The main purpose of a quantum key distribution network is to provide secret keys to any users or applications requiring a high level of security, ideally such as to offer the best protection against any computational attack, even of a quantum nature.

Twin-field quantum key distribution with passive-decoy state
New Journal of Physics, 2020 Twin-Field quantum key distribution (TF-QKD) and its variants, e.g. phase-maching QKD, sending-or-not-sending QKD, and no phase post-selection TFQKD promise high key rates at long distance to beat the rate distance limit without a repeater.
