Security of quantum key distribution with light sources that are not independently and identically distributed

2016 · Physical Review A

Although quantum key distribution (QKD) is theoretically secure, there is a gap between the theory and practice. In fact, real-life QKD may not be secure because component devices in QKD systems may deviate from the …

Quantum key distribution with setting-choice-independently correlated light sources

2019 · npj Quantum Information

Abstract Despite the enormous theoretical and experimental progress made so far in quantum key distribution (QKD), the security of most existing practical QKD systems is not rigorously established yet. A critical obstacle is that almost …
