Nadjib Benchabane

Nadjib Benchabane is a PhD student in the QuNES team at Institut Néel (CNRS/UGA, Grenoble), supervised by Benjamin Sacépé and Hermann Sellier. He holds an MSc in Quantum Information and Quantum Engineering from Université Grenoble Alpes and a physics teaching diploma from the École Normale Supérieure de Constantine. His research focuses on the fabrication and characterization of graphene-based Josephson junctions operating in the quantum Hall regime, including spin-polarized states. Using gate-defined geometries and low-temperature transport, he probes Andreev processes to establish reproducible QH–superconductor hybrids. The broader goal is to uncover phase-coherent signatures compatible with topological superconductivity and to provide device design rules for future graphene-based quantum circuits.
