The properties of light which could not be explained through classicö’s cat". In celebration of the International Year of Light, join Nobel Laureate Serge Haroche to explore these quantum phenomena, the role of light in an explosion of discovery and possible applications of the counter-intuitive quantum logic. Serge Haroche is a French physicist who was awarded the 2012 Nobel Prize for Physics jointly with David J. Wineland for "ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems", a study of the photon. He is now professor of quantum physics at Collège de France, where he is also the president of the institution.
