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).

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.

Zero-error attack against coherent-one-way quantum key distribution
New Journal of Physics, 2021 Coherent-one-way (COW) quantum key distribution (QKD) held the promise of distributing secret keys over long distances with a simple experimental setup. Indeed, this scheme is currently used in commercial applications.

The Case for Quantum Key Distribution [PDF]
, 2009 Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures.

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.

Phase-Matching Quantum Key Distribution
Physical Review X, 2018 Quantum key distribution allows remote parties to generate information-theoretic secure keys. The bottleneck throttling its real-life applications lies in the limited communication distance and key generation speed, due to the fact that the information ...

Higher-rate relativistic quantum key distribution
Scientific Reports, 2021 One of the major problems in the field of quantum key distribution (QKD) is the low key rates at which the systems operate. The reasons for this are the processes used to ensure the key distribution itself: sifting, parameter estimation, key ...

Practical issues of twin-field quantum key distribution
New Journal of Physics, 2019 Twin-field quantum key distribution(TF-QKD) protocol and its variants, such as phase-matching QKD, sending-or-not-sending QKD and no phase post-selection TF-QKD(NPP-TFQKD), are very promising for long-distance applications.
