AbstractIn this paper, we propose a dynamical approach based on the Gorini–Kossakowski–Sudarshan–Lindblad equation for a problem of decision making. More specifically, we consider what was recently called a quantum parliament, asked to approve or not a certain law, and we propose a model of the connections between the various members of the parliament, proposing in particular some special form of the interactions giving rise to a collaborative or noncollaborative behavior.
