Quantum key distribution with post-processing driven by physical unclonable functions [PDF]
Appl. Sci. 14(1), 464, (2024), 2023 Quantum key-distribution protocols allow two honest distant parties to establish a common truly random secret key in the presence of powerful adversaries, provided that the two users share beforehand a short secret key. This pre-shared secret key is used mainly for authentication purposes in the post-processing of classical data that have been obtained

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.

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.

A fully passive transmitter for decoy-state quantum key distribution [PDF]
Quantum Science and Technology, 2022 A passive quantum key distribution (QKD) transmitter generates the quantum states prescribed by a QKD protocol at random, combining a fixed quantum mechanism and a post-selection step.

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).

Practical continuous-variable quantum key distribution with composable security [PDF]
Nature Communications, 2021 A quantum key distribution (QKD) system must fulfill the requirement of universal composability to ensure that any cryptographic application (using the QKD system) is also secure.
