Methods in Implementing 2 Dimensional Arrays of Ion Traps — •Muir Kumph¹, Michael Niedermayr¹, Regina Lechner¹, Michael Brownnutt¹, and Rainer Blatt² — ¹Institut für Experimentalphysik, Innsbruck, Austria — ²Institut für Quantenoptik und Quanteninformation, Innsbruck, Austria

Microfabricated ion traps are one of the most promising candidates for a scalable quantum mechanical computer. In such a system, individual ions can be held with long coherence times, while allowing the ions to interact in a controlled way via laser mediated gates (eg.Molmer-Sorensen). 2D arrays of ion traps open up new possibilities of gate operation and algorithm implementation. Investigating a mesoscopic scale, low-count array, surface ion trap, we look at the feasibility of addressing the ions by magnetic fields, micro-lens arrays and tightly-focussed free-space light. Adjacent linear Paul traps as well as 2 dimensional arrays of ring traps are discussed in relation to the above addressing techniques. Methods for driving the array of micro ion traps in a cryostat via novel radio frequency resonators are also to be highlighted.
