Professor
Born in 1947, Alain Aspect is an alumni of ENS Cachan and Université d'Orsay. He has held positions at Institut d'Optique, ENS Yaoundé (Cameroon), ENS Cachan, ENS/Collège de France, CNRS. He is currently a professor at Institut d'Optique Graduate School (Augustin Fresnel chair), and at Ecole Polytechnique, in Palaiseau. He is a member of several science academies in France, USA, Austria, Belgium, UK. Among several awards, he has received the CNRS Gold medal (2005), the Wolf Prize in Physics (2010), the Balzan prize on quantum information (2013), the Niels Bohr Gold medal (2013), the Albert Einstein medal (2013), the Ives medal of the Optical society of America (2013). Alain Aspect research has borne on tests of Bell's inequalities with entangled photon (PhD, 1974-1983), wave-particle duality for single photons (1984-86, with Philippe Grangier); laser cooling of atoms with lasers below the one photon recoil (1985-1992, with Claude Cohen-Tannoudji); ultra-cold atoms, quantum gases, and quantum simulators (1992- , in the Atom Optics group he has established at Institut d'Optique).
Expert in Quantum Optics and Cavity QED
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.
