Optimal control of ultracold atomic quantum systems — •Antonio Negretti1, Simone Montangero2, Tommaso Calarco2, Sandrine van Frank3, Wolfgang Rohringer3, Tarik Berrada3, Thorsten Schumm3, and Jörg Schmiedmayer3 — 1Zentrum für Optische Quantentechnologien, Universität Hamburg, Luruper Chaussee 149, 22761 Hamburg (Germany) — 2Institut für Quanteninformationsverarbeitung, Universität Ulm, Albert-Einstein-Alle 11, 89069 Ulm (Germany) — 3Atominstitut, Universität Wien, Stadionallee 2, 1020 Wien (Austria)
In the recent past, experiments with ultracold quantum gases have reached an extremely high degree of control, in which the manipulation and detection of single particles like atoms and ions have been demonstrated. For the purposes of quantum information processing and interferometry it is needed not only a high degree of control, but also that the desired quantum transformation is obtained as fast as possible. To this aim optimal control is a valuable resource to achieve high performance in the shortest possible time.
In my talk I shall present recent and very promising achievements in the optimized quantum dynamics of degenerate quasi 1D quantum Bose gases experiments.
