Dr. Philippe St Jean

Biography

Philippe St-Jean holds a research chair from the Ministry of Economy and Innovation of Quebec in quantum photonics. His team's main research interests are related to the experimental study of light-matter interaction, both in the quantum regime and in photonic systems with elements of exotic symmetry. The ultimate goal of this work is twofold: to design new robust photonic devices for applications in quantum technologies, and to explore the emergence of new phases of matter (e.g., topological or strongly correlated) using photonic emulators. His young research group aims to extend this topological photonics to the quantum regime, both for applications in quantum technologies and to investigate the emergence of new phases involving collective excitations. The main research projects currently underway include: 1. Strong light-matter coupling in topological systems for the robust generation of non-classical photonic states; 2. Emulation of unconventional topological phases in quantum walk processes with correlated photon pairs; 3. Optimization of topological photonic structures using advanced computational tools such as inverse design and machine learning; 4. Chiral quantum optics in dense ensembles of quantum emitters.
