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…

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…

Quantum key distribution with imperfectly isolated devices
Xoel Sixto, Ãlvaro Navarrete, Margarida Pereira +3
Most security proofs of quantum key distribution (QKD) assume that there is no unwanted information leakage about the state preparation process. However, this assumption is impossi…
