Experimental quantum computation with trapped ions

Philipp Schindler

Institute for Experimental Physics, University of Innsbruck

Nowadays it is widely known that a quantum computer can solve certain problems more efficient than any classical computer. In the group of Prof. Rainer Blatt in Innsbruck we try to realize such a quantum computer with the aid of trapped Ca+ ions. In the last year quantum state manipulation of a few trapped ions has evolved beyond the set of coherent universal quantum operations towards an efficient toolbox covering also dissipative processes. In this talk I will introduce our toolbox and talk about experiments in the field of quantum computation and quantum simulation. More specifically I will talk about the demonstration of repetitive quantum error correction [1] and the implementation of first steps towards a universal quantum simulator for open quantum systems [2].
