Local manipulations, control and measurements are a prerequisite for employing many-body systems in quantum information processing. However, realizations of many-body systems with these properties so far appeared to be difficult and, as a consequence, new physical phenomena, they could give rise to, remain largely unexplored.In this project, the theory for the experimental generation of locally manipulate-, control- and measurable effective many-body systems in arrays of micro-cavities will be developed and new phenomena these systems give rise to will be explored.Thorough studies of the feasibility of the suggested experiments will be performed and detailed proposals for their realization developed. The thus generated, locally addressable, effective many-body systems offer the possibility to deliberately design and control inhomogeneities. The new physical phenomena, this can bring forth, will be explored and schemes to study them experimentally in arrays of micro-cavities will be developed. These investigations will be completed by detailed studies of dissipation and local measurements in interacting systems. The former will require developing a new technique to model it, whereas the latter can show an interesting energy transfer into the measured system. The developed techniques will then be applied to explore an interrelation between the possibility to cool a many-body system and its potential for solving computational problems in adiabatic quantum computation.
