Linear chains of trapped ions are used for quantum simulation of 1D spin systems [1]. 2D arrays of ion traps may allow to extend the range of accessible simulations to systems with more than one spatial dimension, because of the physical arrangement of the individual trapping sites. We have realized a microfabricated 2D array of individual RF point traps with a 100 micron pitch between trapping sites. The inter-ion distance may be reduced while maintaining a stable trap by varying the RF amplitude on electrodes between two adjacent trapping sites [2]. In this way, coherent operations mediated by the Coulomb interaction should become possible. We report on our progress towards operating the system at cryogenic temperatures and present surface trap designs for a new generation of 2D arrays based on parallel linear traps.
