Finite-size security of continuous-variable quantum key distribution with digital signal processing

While continuous-variable QKD presents many experimental advantages, a full security proof that addresses the most general attacks and digitized signals in the finite-size regime has so far been lacking. Here, the authors fill this gap in the case of a protocol with a binary phase modulation.
