Michel Brune

Michel Brune is a Professor at École Polytechnique, specializing in quantum optics and cavity quantum electrodynamics (QED). He graduated from École Normale Supérieure and completed his PhD on the realization of a two-photon micromaser under the guidance of Serge Haroche. Following his doctoral work, he became a permanent researcher at the CNRS, working within the cavity QED team led by Haroche and Jean-Michel Raimond.Dr. Brune has conducted pioneering experiments involving high-Q superconducting microwave resonators and circular Rydberg atoms, which serve as sensitive probes of cavity radiation fields. His research has led to significant advancements in quantum measurement, including experiments demonstrating the collapse of quantum states, repeatability of measurements, and the observation of quantum jumps in light. He has also prepared "Schrödinger cat" states and studied their decoherence, exploring the boundaries between quantum mechanics and classical physics.
