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…
Security bounds for unidimensional discrete-modulated CV-QKD: a Gaussian extremality approach
John A. Mora RodrÃguez, Maron F. Anka, Leonardo J. Pereira +2
Unidimensional (1D) Gaussian-modulated continuous-variable quantum key distribution protocols have been proposed as a way to simplify implementation and reduce costs through single…
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…
An introductory review of the theory of continuous-variable quantum key distribution: Fundamentals, protocols, and security
Maron F Anka, John A. Mora RodrÃguez, Douglas F. Pinto +3
Continuous-variable quantum key distribution (CV-QKD) has emerged as a promising approach for secure quantum communication, offering advantages such as high key generation rates, c…
