Ion traps are a promising tool for quantum simulations [1]. The possibility of producing superposition states as well as entanglement between qubits allows, in principle, to efficiently run simulations that are not tractable for classical computers.
Currently, simulations are typically implemented using strings of ions. However, certain problems such as the 2D Ising model [2] would be simulated more naturally in a 2D architecture, e.g. in an array of individual ion traps. Furthermore, such arrays are a possible way of implementing a scalable quantum computer [3].
We have proposed a 2D architecture consisting of individual surface traps in which interactions between nearest-neighbour ions can be deterministically switched on and off [4]. Recently we have shown trapping and shuttling of ions in a relatively large array [5]. I will report on our efforts to miniaturize the array in order to increase the coupling between adjacent qubits and realize coherent operations.
