Quantum Key Distribution Beyond Stationary Channels
Vaisakh Mannalath, Víctor Zapatero, Kiyoshi Tamaki +1
Quantum key distribution (QKD) over non-stationary channels, such as satellite links, is characterized by short, high-loss, and strongly fluctuating transmission windows that produ…
Finite-key security analysis of decoy-state QKD with source and detector imperfections
Xoel Sixto, Guillermo Currás-Lorenzo, Margarida Pereira +3
Decoy-state quantum key distribution (QKD) is the most widely adopted approach for overcoming the limitations of imperfect single-photon sources. However, existing security proofs…
Finite-key feasibility of geostationary quantum key distribution
Vaisakh Mannalath, Víctor Zapatero, Marcos Curty
Quantum key distribution (QKD) via geostationary Earth orbit (GEO) satellites offers a compelling route to continuous, continental-scale secure communications. However, operation i…
Device-independent quantum cryptography with input leakage
Víctor Zapatero, Marcos Curty
Device-independence is the gold standard of quantum cryptography. To meet this standard, a central assumption is that no information leakage occurs during protocol execution. We re…
Elementary Tail Bounds on the Hypergeometric Distribution
Vaisakh Mannalath, Víctor Zapatero, Marcos Curty
We use a simple method to derive two concentration bounds on the hypergeometric distribution. Comparison with existing results illustrates the advantage of these bounds across diff…
Quantum key distribution overcoming practical correlated intensity fluctuations
Jia-Xuan Li, Feng-Yu Lu, Ze-Hao Wang +8
Intensity correlations between neighboring pulses open a prevalent yet often overlooked security loophole in decoy-state quantum key distribution (QKD). As a solution, we present a…
