Application of Quantum Optimal Control to Quantum Technologies
Prof. Dominique Sugny (Laboratoire Interdisciplinaire Carnot de Bourgogne, Dijon)

We apply innovative tools coming from quantum optimal control theory to improve theoretical and experimental techniques in quantum technologies [1,2]. This approach allows us to explore and to experimentally reach the physical limits of the corresponding dynamics in the presence of typical experimental imperfections and limitations. After a pedagogical introduction to these techniques [3], different applications in quantum technologies will be described. Recent theoretical and experimental results for the control of a Bose-Einstein Condensate in an optical lattice will be presented [4].
