Tighter Asymptotic Key Rates for Intensity-Correlated Decoy-State QKD via Nonlinear Programming
Matej Pivoluska, Mateus Araújo
Decoy-state QKD with phase-randomized weak coherent pulses is typically analyzed assuming independent, precisely prepared intensities. Real sources, however, can exhibit correlated…
Finite-size quantum key distribution rates from Rényi entropies using conic optimization
Mariana Navarro, Andrés González Lorente, Pablo V. Parellada +2
Finite-size general security proofs for quantum key distribution based on Rényi entropies have recently been introduced. These approaches are more flexible and provide tighter bou…
Post-selection games
VÃctor Calleja RodrÃguez, Ivan A. Bocanegra-Garay, Mateus Araújo
In this paper, we introduce post-selection games, a generalization of nonlocal games where each round can be not only won or lost by the players, but also discarded by the referee.…
Optimal key rates for quantum key distribution with partial source characterization
Margarida Pereira, Guillermo Currás-Lorenzo, Mateus Araújo
Numerical security proofs based on conic optimization are known to deliver optimal secret-key rates, but so far they have mostly assumed that the emitted states are fully character…
