Abstract:

Direct experimental access to some of the most intriguing and puzzling quantum phenomena is difficult due to their fragility to noise. Their efficient simulation on conventional computers is impossible, since quantum behaviour is not efficiently translatable in classical language. However, one could gain deeper insight into complex quantum dynamics via experimentally simulating the quantum behaviour of interest in another quantum system, where not all but the relevant parameters and interactions can be controlled and robust effects detected sufficiently well. One example is simulating quantum-spin systems with trapped ions. Here, we explore the limitations and prospects for scaling to larger and two dimensional systems, aiming to span a triangular lattice by individual ion traps above 2D-electrodes of micrometer scale. On the other hand, we are studying the onset of thermalisation and its time scales in closed quantum systems.
