Physics is fascinating because of the intellectual excitement it provides and because of the applications it offers. In the Group of Applied Physics (GAP) at Geneva University we get our inspiration from both of these motivations. Optics, in this respect, has a privileged place. Indeed, in modern optics, experiments and theory progress hand-in-hand, and practical applications are close behind. Consequently, we can work both on conceptual issues and on applications. Moreover, it is a very good time for optics! The fascinating new insight about quantum mechanics brought about by recent quantum optics experiments on one side, and the tremendous development of optical communications on the other, illustrates our privileged position.
The Centre for Quantum Information and Communication (QuIC) at the Université Libre de Bruxelles has been working on quantum information theory for several years, with research contributions ranging from fundamental questions such as quantum measurement, quantum entanglement, or quantum nonlocality to more information-flavored issues such as quantum cloning, quantum cryptography, or quantum algorithms. More recently, it has also started an experimental quantum information activity together with the ULB optics laboratory. It currently holds two provisional patents, and has published numerous scientific papers among which two in the journal Nature.
A large fraction of QuIC research activities over the last few years has focused on quantum information with continuous-variable carriers. In particular, the QuIC has reported on the first demonstration of continuous-variable quantum key distribution in collaboration with the Institut d'Optique Palaiseau. The QuIC initiated in 2002 a series of conferences especially devoted to continuous-variable quantum information processing, which now runs on an annual basis, and has been coordinating European research projects on this topic since 2004.
QuantumWorks is an NSERC-funded Innovation Platform that links Canadian researchers with industrial and government agency partners to lead Canada into the next technological revolution - that of Quantum Information Processing (QIP).
