Homodyne-detector-blinding attack in continuous-variable quantum key distribution

H Qin, R Kumar, V Makarov, R Alléaume - Physical Review A, 2018‏ - APS
We propose an efficient strategy to attack a continuous-variable (CV) quantum key
distribution (QKD) system, which we call homodyne detector blinding. This attack strategy …

Self-coherent phase reference sharing for continuous-variable quantum key distribution

A Marie, R Alléaume - Physical Review A, 2017‏ - APS
We develop a comprehensive framework to model and optimize the performance of
continuous-variable quantum key distribution (CV-QKD) with a local local oscillator (LLO) …

Quantum hacking on a practical continuous-variable quantum cryptosystem by inserting an external light

H Qin, R Kumar, R Alleaume - Electro-Optical and Infrared …, 2015‏ - spiedigitallibrary.org
We report here a new side channel attack on a practical continuous-variable (CV) quantum
key distribution (QKD) system. Inspired by blinding attack in discrete-variable QKD, we …

[HTML][HTML] Improving the maximum transmission distance of self-referenced continuous-variable quantum key distribution using a noiseless linear amplifier

Y Wang, X Wang, D Huang, Y Guo - Entropy, 2018‏ - mdpi.com
We show that a noiseless linear amplifier (NLA) can be placed properly at the receiver's end
to improve the performance of self-referenced (SR) continuous variable quantum key …

Sécurité pratique de systèmes de cryptographie quantique: étude d'attaques et développement de contre-mesures

H Qin - 2015‏ - pastel.hal.science
Dans cette thèse, j'étudie une primitive cryptographique appelée distribution quantique de
clés. La distribution quantique de clés permet à deux parties distantes de partager une clé …
