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. Here we report on the design and fabrication of linear ion traps that are arranged in a two-dimensional lattice on a microchip. The linear traps are segmented to create multiwells along the trap axes. An interaction zone allows to reduce the distance between adjacent wells along the axis to about 40 µm using DC control fields. In this way, coherent operations mediated by the Coulomb interaction should become possible [2]. Similarly, the distance between adjacent multiwells can be reduced in the direction perpendicular to the trap axes by tuning the RF voltage [3]. Additionally, the multiwells can be moved independently of each other along the trap axes. This scheme should enable digital simulation of spin systems with next-neighbor interactions on a square lattice as well as triangular lattices. [1] C.
