Preprocessing noise in finite-size quantum key distribution
Gabriele Staffieri, Giuseppe D'Ambruoso, Giovanni Scala +1
It is known that preprocessing noise may boost quantum key distribution by expanding the range of values of tolerated noise. For BB84, adding trusted noise may allow the generation…

Finite-size secret-key rates of discrete modulation continuous-variable quantum key distribution under Gaussian attacks
Gabriele Staffieri, Giovanni Scala, Cosmo Lupo
Quantum conditional entropies play a fundamental role in quantum information theory. In quantum key distribution, they are exploited to obtain reliable lower bounds on the secret-k…

Finite-size security of QKD: comparison of three proof techniques
Gabriele Staffieri, Giovanni Scala, Cosmo Lupo
We compare three proof techniques for composable finite-size security of quantum key distribution under collective attacks, with emphasis on how the resulting secret-key rates beha…
