Scaling up ion-trap quantum computers and new directions in quantum simulations. — •Christian Schmiegelow, Thomas Ruster, Henning Kaufmann, Marco Dillmann, Claudia Warschburger, Ferdinand Schmidt-Kaler, and Ulrich Poschinger — QUANTUM, Institut für Physik, Johannes Gutenberg Universität Mainz, Staudingerweg 7, 55128 Mainz

We present a full set of tools for scalable quantum computing on microstuctured linear Paul traps. We put together cold ion splitting and transport with entangling- and single-qubit gates to achieve addressing by moving the ions in and out of the lasers. With this platform we test the resistance of a magnetic Decoherence-Free-Subspace to ion separations of above 5mm. We'll also present our advances in scaling up to more ions and gates between Decoherence-Free qubits. Finally we'll introduce some new directions into quantum simulations which include 2D spectroscopy and measurement of time correlation functions.
