Juggling with Photons in a Box to Explore the Quantum World
We observe non destructively photons trapped in a high Q cavity, generate quantum fields in “Schrödinger cat” like states and study their decoherence. Application of these studies to the processing of quantum information will be discussed.
Serge Haroche was born in 1944 in Casablanca and graduated from Ecole Normale Supérieure (ENS), receiving his doctorate from Paris VI University in 1971. After a post-doctoral visit to Stanford University (1972-73), he became full professor at Paris VI University in 1975, a position he held until 2001, when he was appointed Professor at Collège de France. Since September 2012, he is the President (Administrateur) of this institution.
Haroche’s research has mostly taken place in the laboratory Kastler Brossel at ENS. His main research activities have been in quantum optics and quantum information science. He has made important contributions to Cavity Quantum Electrodynamics (Cavity QED), the domain of quantum optics which studies the behaviour of atoms interacting strongly with the field confined in a high-Q cavity. An atom-photon system isolated from the outside world by metallic walls realizes a very simple experimental model which Serge Haroche and his team have used to test fundamental aspects of quantum physics such as state superposition, entanglement, complementarity and decoherence.
Serge Haroche has received many prizes and awards, culminating in the 2012 Nobel Prize in physics, shared with David Wineland.

Can the Future of Accelerators Be Fibers? The Optics Road to GeV Scientific and Societal Applications
We report on a revolutionary laser architecture that makes possible for the first time to accelerate particles to very high energy(GeV) at high repetition rate(kHz) with good efficiency. Based on massively parallel coherent fiber amplifiers the technique (CAN Coherent Amplification Network architecture) has the potential to produce simultaneously, petawatt peak power with megawatt average power with >30% efficiency. CAN transitions Optics from the eV to the GeV regime and beyond and could be the gateway to grand scientific and societal applications notably, particle collider, Higgs factory, nuclear transmutation, nuclear pharmacology, free-electron laser and more.
Gerard A. Mourou is Professor, member of the Haut Collège at the Ecole Polytechnique(France), Professor at the University of Nizhny Novgorod (Russia) and A.D. Moore Professor Emeritus at the University of Michigan. He is also Director of the newly created Center IZEST(International Center for Zettawatt-Exawatt Science and Technology) at the Ecole Polytechnique. He spent most of his career at the Universities of Rochester and Michigan Ann Arbor. He is recognized as a pioneer in the field of ultrafast Optics and ultra intense laser where he demonstrated,the techniques of THz generation, picosecond electron diffraction, electrooptics sampling and femtosecond ophthalmology. With Donna Strickland he showed the technique of Chirped Pulse Amplification, fulcrum of Ultrahigh field science. He was the initiator and coordinator of the Extreme Light Infrastructure (ELI). Recently he proposed a novel laser architecture CAN(cCoherent Amplifying Network) susceptible to provide not only PW peak power with MW average power and good efficiency. As the head of the International consortium ICAN, he validated the concept that could make the laser entry to sub-nuclear and particle physics possible.
