Álvaro Navarrete attained his B.Sc. in Telecommunication Technologies Engineering from the University of Vigo in 2015, receiving the best academic record award from the University of Vigo and the Regional Government of Galicia. In 2016, he completed an M.Sc. in Laser and Photonics from a joint program offered by the universities of Santiago de Compostela, Vigo, and A Coruña. He was then granted a FPU scholarship to pursue his Ph.D. studies at the University of Vigo, focusing on investigating the security and performance aspects of quantum key distribution systems under the guidance of Prof. Marcos Curty. He successfully defended his Ph.D. thesis in 2021 and currently serves as a postdoctoral researcher at the Vigo Quantum Communication Center (VQCC). His main research interests revolve around the domain of quantum communication. To date, he has co-authored a dozen high-impact publications, predominantly delving into the analysis of quantum key distribution protocols, with a special emphasis on the implementation security problem.
