Exploring the ultimate limits of control: Quantum networks for non-classical information processing

The down-scaling of electronic devices has been an unprecedented success-story over the last decades. This development has, to a large extent, been based on continuous improvements of structural control. As we approach nanoscopic (atomic) precision, the question arises whether dynamical control (function) will be able to follow down to these ultimate limits, i.e. whether the exploitation of the fundamental rules of quantum dynamics will become possible at large scale. To approach this goal there are at least two different paradigms which could be exploited: "Selective control" and "collective control". The latter should be an interesting alternative for nanoscopic quantum networks.
