The experimental observation of quantum phenomena in strongly correlated many particle systems is difficult because of the short length-and timescales involved. Obtaining at the same time detailed control of individual constituents appears even more challenging and thus to date inhibits employing such systems as quantum information processing devices. Substantial progress has been achieved with Josephson junction arrays and cold atoms in optical lattices, where a detailed control of collective properties is feasible. However it is very difficult to address and hence control or measure individual sites.
