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…
Towards a point-to-point CV-QKD system: Implementation challenges and perspectives
Davi Juvêncio Gomes de Sousa, Nelson Alves Ferreira Neto, Christiano M. S. Nascimento +7
This article presents an analysis of the practical challenges and implementation perspectives of point-to-point continuous-variable quantum key distribution (CV-QKD) systems over o…
Digital Signal Processing from Classical Coherent Systems to Continuous-Variable QKD: A Review of Cross-Domain Techniques, Applications, and Challenges
Davi Juvêncio Gomes de Sousa, Caroline da Silva Morais Alves, Valéria Loureiro da Silva +1
This systematic review investigates the application of digital signal processing (DSP) techniques -- originally developed for coherent optical communication systems to continuous-v…
