A promising way to realise quantum simulations is based on trapped ions. Advanced micro-fabrication techniques and geometrical optimisation allows the construction of two-dimensional surface-electrode trap arrays [1] that may be used as large-scale simulators [2]. Prerequisites for such implementations are high-fidelity control of all motional degrees of freedom and a high-level of mode stability.
We present measurements of the stability of mode frequencies of a single 25Mg+ ion trapped in one out of three sites, which are arranged in an equilateral triangle and separated by 40 µm. Our results are discussed in the context of future experiments, where we aim to establish inter-ion Coulomb couplings between all three trap sites.
