Quantum Communication, Quantum Memories, Quantum Metrology

Our research is devoted to the study and development of quantum functionalities in semiconductor systems using the nanofabrication techniques of opto-electronics. We develop high performances integrated sources of quantum light, non-linear devices operating at the single photon level, spin-based quantum memories and optomechanical platforms for quantum information processing.

The group conducts theoretical research on correlated quantum systems. Our main efforts focus on the physics of systems that constitute promising plateforms for concrete realization of quantum technologies. Together with other systems in condensed matter and quantum optics, ultracold atoms have already produced milestone results, which turn quantum technologies from dream to reality.

Diamond’s nitrogen-vacancy (NV) centers show great promise in sensing applications and quantum computing due to their long electron spin coherence time and their ability to be located, manipulated and read out using light. In our group, we apply femtosecond laser microfabrication to write optical waveguides and NV centers in single-crystal synthetic diamond.
