CV-QKD has been my main subject of research during the last years, focusing mainly on practical implementation aspects. My main task is to improve the previous proof-of-principle CV-QKD prototypes to setups in consonance with current classical coherent optical communication systems, providing important advantages in terms of performance, deployment and cost. A second objective of my research is to study the performance of integrated devices in CV-QKD and, in a more theoretical approach, their performance in satellite scenarios.
