Trapped ions as quantum bits: Essential numerical tools — •Kilian Singer1, Ulrich G. Poschinger1, Michael Murphy2, Frank Ziesel1, Tommaso Callarco2, and Ferdinand Schmidt-Kaler1 — 1Universität Mainz, Staudingerweg 7, 55128 Mainz — 2Universität Ulm, Albert-Einstein-Allee 11, 89069 Ulm
We present powerful numerical tools for the optimization of the external control of the motional and internal states of trapped neutral atoms, explicitly applied to the case of trapped laser-cooled ions in a segmented ion-trap [1]. We then solve inverse problems, when optimizing trapping potentials for ions. Optimizing a quantum gate is realized by the application of quantum optimal control techniques. The numerical methods presented can also be used to gain an intuitive understanding of quantum experiments with trapped ions by performing virtual simulated experiments on a personal computer [2].
