Romain Alléaume, Principal Scientist - Cofounder

Romain Alléaume Dr Romain Alléaume graduated from Ecole Normale Supérieure of Paris in 2001 and completed his PhD at the University of Paris VI and ENS Cachan in 2004, on experimental quantum cryptography with single-photon sources. Based on his PhD work, he was co-recipient, together with 5 co-workers, of “magazine La Recherche” scientific prize 2004. Since September 2004, he has been working at Telecom ParisTech, in the Network and Computer Science Department, where he has initiated the research activity on quantum information. He has been responsible, during the period 2004-2008 of the scientific and administrative management of the network (NET) subproject of the FP6 European Integrated project SECOQC. He is also the coordinator, for Telecom ParisTech, of two national projects on quantum key distribution: PROSPIQ and SEQURE.

Sébastien Kunz-Jacques, Chief Technical Officer

Sébastien Kunz-Jacques Sébastien Kunz-Jacques graduated from the ENS Paris in 2001 and from Télécom ParisTech in 2003. He then worked for four years in the cryptology laboratory of the ANSSI, the French national agency for the evaluation of the security of IT products. In this position, he participated in several Common Criteria evaluations of products involving cryptographic mechanisms. He contributed to several research publications and obtained a PhD in cryptology from the ENS Paris crypto laboratory and the University of Paris VII in 2007.

Board of advisors

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.
