🏆 We are kicking off a new edition of the ESET Science Award by introducing the Chair of the international jury that will select this year’s laureates. This year, the role will be taken on by French physicist and Nobel Prize laureate Serge Haroche. He was awarded the 2012 Nobel Prize in Physics, together with David J. Wineland, for pioneering experimental methods that enable the measurement and manipulation of individual quantum systems. ⚛️ Serge Haroche is a leading figure in the fields of quantum optics and cavity quantum electrodynamics. He is renowned for pioneering experimental methods that make it possible to observe, measure and manipulate individual quantum systems. His research has focused on the fundamental interaction between matter and radiation, opening up new possibilities for studying individual photons without destroying them and for directly testing the laws of quantum mechanics through experiments. 🔬 Find out more at: esetscienceaward.com #ESETScienceAward #ESETScience #Science #Research #Innovation
