Bio

Víctor Zapatero completed his bachelor’s degree in Fundamental Physics at the Universidad Complutense de Madrid in 2015, and obtained a master’s degree in Theoretical Physics from the same university in 2016. That same year, he started a PhD position at the University of Vigo, where he was later on granted with an FPU scholarship to carry out his doctoral thesis on the security of quantum key distribution systems. His thesis dissertation was presented by the end of 2021, obtaining his doctorate with honors. Since then, he occupies a postdoc position in the same university, and his main research topic is quantum cryptography.
