Ions confined in linear Paul traps have proven to be well suited for analogue quantum simulations. While in proof-of-principle experiments the adiabatic evolution of quantum magnets has been simulated with linear chains of two [1] and later with up to nine ions [2], scalability of ion based quantum simulators remains a major issue.

To overcome the limitations of one-dimensional linear Paul traps, novel two-dimensional surface traps for triangular arrays of ions have been proposed [3] and optimized [4]. While the ions will be stored in individual potential minima, the mutual distances should be small enough to provide a sufficient coupling strength for quantum simulation experiments in two dimensional lattices [5]. We will report on the current status of the experimental setup and will present first proposals for quantum simulations that could be envisioned [6].
