For reliable quantum devices, effective regulation of open quantum systems is vital. In particular, a profound understanding of the interplay between the environment and the regulation is crucial. In this context, it has been shown, that environment and regulation need not to be antagonistic, but their interaction exhibits cooperative effects. To examine the underlying principles of (self-) regulation in open quantum systems, we reformulate the regulation process in terms of quantum information theory. We investigate the role quantum correlations play in this setting. This also addresses the question, how quantum correlations can be exploited to reach the thermodynamic limits of regulation.
