Quantum Key Distribution Beyond Stationary Channels
Vaisakh Mannalath, VÃctor 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, VÃctor 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…
Intensity correlations in decoy-state BB84 quantum key distribution systems
Daniil Trefilov, Xoel Sixto, VÃctor Zapatero +3
The decoy-state method is a prominent approach to enhance the performance of quantum key distribution (QKD) systems that operate with weak coherent laser sources. Due to the limite…
Device-independent quantum cryptography with input leakage
VÃctor 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, VÃctor 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…
