Anaïs Dréau winner of the Gustave Ribaud Prize of the French Academy of Sciences
On October 28th, 2025, Anaïs Dréau, CNRS Researcher at L2C, received the Gustave Ribaud Prize from the French Academy of Sciences. Each year, the Academy awards nearly eighty prizes covering all areas of science, both fundamental and applied.
After completing her PhD at the Laboratory of Quantum and Molecular Photonics in Cachan in 2013, Anaïs Dréau carried out postdoctoral research at Delft University of Technology (The Netherlands). She joined the CNRS in 2016, in the Charles Coulomb Laboratory (L2C), within the Solid-State Quantum Technologies team.
There, she explores the quantum properties of individual fluorescent crystal defects in semiconductor materials such as silicon — defects that may prove useful for emerging quantum technologies. By studying them one by one through optical microscopy at cryogenic temperatures, she seeks to understand their quantum behavior. Her work focuses in particular on stabilizing their single-photon emission at telecom wavelengths and controlling their magnetic spin properties.
