The activities of the theory group of
GAP-Optique are twofold. On the one hand, we work in close collaboration
with the other members of GAP to provide them with theoretical support.
This is a very enriching task for everybody, since it bridges the gap
between the mathematical, abstract rigor of the theoretician, and the
intuitive arguments that the experimentalist derive from their activities
in the lab. On the other hand, we are working on several topics of
quantum information theory. In choosing the themes for these
investigations, we try to keep a good balance between
"foundations" and "applications". In this sense, one
of the more interesting results recently is the discovery that the
violation of Bell's inequalities detects entanglement strong enough to be
"useful" for cryptography, teleportation and other applications
of quantum information processing.
