Abstract
We propose and analyze a possible implementation of Maxwell's demon (MD) based on a single-electron pump. It presents a practical realization of MD in a solid-state environment. We show that measurements of the charge states of the pump and feedback control of the gate voltages lead to a net flow of electrons against the bias voltage ideally with no work done on the system by the gate control. The information obtained in the measurements converts thermal fluctuations into energy stored in a capacitor. We derive the conditions on the detector back action and measurement time necessary for implementing this conversion.Description
