Control of decoherence with no control [PDF]
Common philosophy in control theory is the control of disorder by order. It is not exceptional for strategies suppressing quantum decoherence. Here we predict an anomalous quantum phenomenon. Suppression of decoherence can be made via more disordered white noise field, in particular white Poissonian noise.

A child was considered as infected with H pylori if the optical density of the ELISA

What is the motivational effect of imposing a minimum effort requirement? Agents may no longer exert voluntary effort but merely meet the requirement. Here, we examine how such hidden costs of control change when control is considered legitimate. We study a principal-agent model where control signals the expectations of the principal and the agent ...
