Quantum Optics Experiments in a Segmented Microchip Ion Trap — •Ulrich Poschinger, Gerhard Huber, Andreas Walther, Max Hettrich, Markus Deiss, Frank Ziesel, Kilian Singer, and Ferdinand Schmidt-Kaler — Institut für Quanteninfarmationsverarbeitung, Universität Ulm, Albert-Einstein-Allee 11, 89069 Ulm
We present recent results from our experiment aiming at scalable quantum simulation and information. We first show how a qubit is implemented by using the Zeeman split groundstate levels of a 40Ca+ ion. Emphasis is put on how the challenging conditions in our microtrap [1] compared to standard traps affect readout, ground state cooling and coherent manipulations [2]. We then present first experiments based on these techniques, including coherent manipulations on two-ion crystals, implementation of spin-dependent and spin-independent light forces, creation and characterization of Schrödinger cat states and quantum state tomography.
