Abstract

Nowadays, quantum key distribution cryptography using continuous variables (CV-QKD) has emerged as a promising approach for the telecommunications industry, owing to its enhanced security and ease of integration with the coherent communication systems currently in use. In this context, this work presents the construction of a classical communication system for testing, with a future goal of transitioning to the quantum regime, focusing on the manipulation of equipment for signal modulation.
