The quantum nature of the physical systems must be taken into account in designing experiments and devices on the microscopic scale. I will first review the main features of a quantum dynamical model and their role in control problems. The unavoidable stochastic character of quantum measurement processes will be highlighted by considering the design of a feedback control strategy. I will then illustrate the possibilities of information feedback in two different problems and settings: The decoupling of a system by its environment using a discrete time feedback strategy and the stabilization of a desired state by means of continuous time feedback.
