Bridging the gap between theory and practice in quantum cryptography
2015 · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE
Quantum key distribution (QKD) needs to close the big gap between theory and practice to be a suitable technology for achieving information-theoretic secure communications. Indeed, recent studies on side-channel attacks have exposed the vulnerabilities of …

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 …

Finite-key security analysis of differential-phase-shift quantum key distribution
2023 · arXiv (Cornell University)
Differential-phase-shift (DPS) quantum key distribution (QKD) is one of the major QKD protocols that can be implemented with a simple setup using a laser source and a passive detection unit. Recently, an information-theoretic security proof …
