One way to gain insight into compex systems, encountered for example in mony-body phenomena, whose behaviour is very hard or even impossible to predict based on analytical models or numerical simulations carried out with classical computation devices, is to map their relevant properties onto a system consisting of individually addressable quantum objects with a well controlled interaction. The behaviour of the original system then can be unveiled by observing the evolution of the tailored quantum system. Such an approach, as proposed by Richard Feynman, is referred to as Quantum Simulation. In principle, different quantum systems, e.g. trapped ions or ultracold quantum gases in specifically designed traps, have been shown to be suitable for such simulations. One of the main outstanding challenges however is the scalability of such approaches to larger numbers of interacting quantum objects that are required to simulate complex systems.

Two very recent approaches towards this goal are based on a novel planar trap geometry featuring arrays of individual radiofrequency traps for atomic ions and optical trapping potentials for ions. Here, both concepts will be introduced and discussed in view of their respective prospects in the field.
