Entanglement-distillation attack on continuous-variable quantum key distribution in a turbulent atmospheric channel

2017 · Physical Review A

The survival of Gaussian quantum states in a turbulent atmospheric channel is of crucial importance in free-space continuous-variable (CV) quantum key distribution (QKD), in which the transmission coefficient will fluctuate in time, thus resulting in …

Security of Continuous-Variable Quantum Key Distribution with Discrete Modulation against General Attacks

2017 · arXiv (Cornell University)

We provide a security analysis of continuous-variable quantum key distribution (CVQKD) with discrete modulation against general attacks in a realistic finite-size regime. To realize this goal, we first prove security of the continuous-variable quantum key …
