Granular superconductors like Nb and NbN and how they can be used to create tunable quantum circuits.

Matéo Vernet has an engineering degree from ESPCI Paris and a master’s degree in Physics of Complex Systems from Université Paris Cité. His research focuses on granular superconductors, such as niobium (Nb) and niobium nitride (NbN) thin films. Combining ion irradiation and electrostatic gating, he studies how geometrical disorder, magnetic impurities, and electrostatic fields change the micro- and macroscopic quantum behavior. In addition, his research encompasses a theoretical approach based on the localization landscape, which will offer novel insights into the spatial inhomogeneity and emergence of superconductivity in disordered and structured systems.
