Philippe Grangier

Philippe Grangier

Philippe Grangier is Directeur de Recherche at the CNRS and Professor at Ecole Polytechnique. His research activities began in 1980 with the realization of experimental tests of Bell's inequalities, under the supervision of Alain Aspect. He obtained a position at CNRS in 1982 in the field of quantum optics, and carried out experimental studies of non-classical properties of light, such as the conditional preparation of a single photon state (PhD thesis, 1986). Then he demonstrated the use of a squeezed-light-enhanced interferometer, and he realized the first observation of pulsed squeezed light (AT&T Bell Labs, USA, postdoc with R.E. Shusher). Since 1988, he has been heading the Quantum Optics group at the Institut d'Optique. Until 1998 he worked on the realization of « Quantum Non-Demolition » (QND) measurements in twitter.com/optics, using atomic non-linear systems, and on reducing the inten-sity noise of laser diodes below the standard shot noise limit. Since 1999, he became involved in many experiments directly related to quantum information processing.

Michel Riguidel

Michel Riguidel

Michel Riguidel is emeritus professor at Télécom ParisTech, where he lectures in security and advanced networks. His research is oriented towards security of Information Systems and Networks, architecture of communication systems (Grids, Next Generation Internet, Active, Ad hoc and configurable Networks), software radio and protocol engineering. Professor Riguidel created the first ITSEC E4 Firewall and has been developing watermarking technology since the early days. He has headed-up many R&D Projects in security: watermarking, PKI, formal methods, critical infrastructure protection. Currently, he is working on security of heterogeneous and mobile systems within Ambient Intelligence and Quantum Networks. He is the Head of the Experts Committee in security at CNRS and belongs to the Executive Board of RNRT (National Network in Telecommunication Research). In the IST Integrated Project of FP6, he is Scientific Director of the Seinit IP(Security Expert Initiative) and Key Researcher of the Secoqc Integrated Project (Development of a Global Network for Secure Communication based on Quantum Cryptography), responsible of the Network Architecture. In Italy, he is scientific member of the international Think tank on telecommunications ThinkTel (www.thinktel.org). Professor Riguidel has several patents in security (firewall, watermarking and protecting CD ROM). Recently, he published “La sécurité à l’ère numérique” (édition Hermès Lavoisier) and “Le téléphone de demain” (édition Le Pommier).

Jean-François Roch

Jean-François Roch

The research career of Jean-François Roch began in 1987, with is PhD on Quantum Non-Destructive measures done at the Institut d'Optique under the direction of P. Grangier. He was then recruited in 1992 by the CNRS as assistant researcher in the Quantum Optics group at the Institut d'Optique. The experiment that he made in 1996, using trapped cold atoms as nonlinear medium, is still today the most efficient QND measure. He then proposed and set up a ''quasi-QND'' experiment using only semiconductor as emitters and receivers. From 1996 to 1998, he worked in the team of S. Laroche, J.-M. Raimond, V. Lefevre-Seguin and J. Hare in the Kastler-Brossel laboratory. There, he was able to observe the intrinsic Kerr bistability of silica microsphere resonators immerged in superfluid helium. Since 1998, he is a professor at the ENS Cachan and the head of the ''Quantum Nanophotonics'' team in the Quantum and Molecular Optics laboratory. He is a junior member of the French ''Institut Universitaire de France'' since 2003, and Deputy Director of the ENS Cachan since january 2009. His research interests include single photon sources and their application to quantum cryptography, and the study of nonlinear optical effects at the nanometer scale.
