Twin-field quantum key distribution with passive-decoy state

open access: yesNew 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

open access: yesNew 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.

High-rate intercity quantum key distribution with a semiconductor single-photon source. [PDF]

open access: yesLight Sci Appl, 2023
Quantum key distribution (QKD) enables the transmission of information that is secure against general attacks by eavesdroppers. The use of on-demand quantum light sources in QKD protocols is expected to help improve security and maximum tolerable loss ...

Breaking the Rate-Loss Bound of Quantum Key Distribution with Asynchronous Two-Photon Interference [PDF]

open access: yesPRX Quantum, 2021
Twin-field quantum key distribution can overcome the secret key capacity of repeaterless quantum key distribution via single-photon interference. However, to compensate for the channel fluctuations and lock the laser fluctuations, the techniques of phase ...

Security of quantum key distribution from generalised entropy accumulation. [PDF]

open access: yesNat Commun, 2023
The goal of quantum key distribution (QKD) is to establish a secure key between two parties connected by an insecure quantum channel. To use a QKD protocol in practice, one has to prove that a finite size key is secure against general attacks: no matter ...

Phase-Matching Quantum Key Distribution

open access: yesPhysical 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 ...

The Case for Quantum Key Distribution [PDF]

open access: yes, 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.
