I joined the Laboratoire de Physique de la Matière Condensée (LPMC) in March 2025 for my M2 internship within the QCMX group. I decided to stay in the same group for my PhD, which I began in September 2025.
The group studies hybrid superconducting circuits to explore new phenomena in condensed matter physics. In particular, it focuses on Josephson junctions consisting of superconducting electrodes bridged by a carbon nanotube (CNT). During my PhD, I will develop a new type of Josephson junction in which the electrodes are made of graphite stacked on niobium diselenide (NbSe₂) and separated by a CNT. Through transport measurements and Andreev bound-state spectroscopy, I aim to investigate signatures of unconventional superconductivity.
Before joining LPMC, I completed my Bachelor’s degree at Sorbonne Université in the intensive physics program called "SPRINT". The following year, I spent an exchange year at ETH Zurich, and later carried out a six-month internship at QuTech, working on a quantum-dot array of six spin qubits. For my Master 2, I joined the QLMN program at Université Paris-Saclay, specializing in condensed-matter physics.
These academic experiences have strengthened my motivation to pursue fundamental research in condensed matter physics using quantum circuits as experimental platforms.
