Fixed Point Exploration For CV-QKD IR QC-MET-LDPC Toward Hardware Implementation

Guilherme Vergne de Oliveira, Mauro Queiroz Nooblath Neto, Micael Andrade Dias +4

High-speed LDPC decoding is a major bottleneck in CV-QKD and motivates hardware acceleration with fixed-point arithmetic. This work compares SPA, MSA, and NMS under a unified low-S…

Neural network for excess noise estimation in continuous-variable quantum key distribution under composable finite-size security

Lucas Q. Galvão, Davi Juvêncio G. de Sousa, Micael Andrade Dias +1

Parameter estimation is a critical step in continuous-variable quantum key distribution (CV-QKD), especially in the finite-size regime where worst-case confidence intervals can sig…
