Device-independent lower bounds on the conditional von Neumann entropy
Peter Brown, Hamza Fawzi, Omar Fawzi
The rates of several device-independent (DI) protocols, including quantum key-distribution (QKD) and randomness expansion (RE), can be computed via an optimization of the condition…

Explicit asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation
Aurélie Denys, Peter Brown, Anthony Leverrier
We establish an analytical lower bound on the asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation of coherent states. Previously…
