The current through nanostructures like quantum dots can be stabilized by a classical feedback loop that continuously adjusts system parameters as a function of the number of tunnelled particles n. At large times, the feedback loop freezes the fluctuations of n, which leads to highly accurate, continuous single particle transfers. For the simplest case of feedback acting simultaneously on all system parameters, we show how to reconstruct the original full counting statistics from the frozen… Expand
Feedback stabilization of pure states in quantum transport
We propose a feedback control scheme for generating and stabilizing pure states of transport devices, such as charge qubits, under non-equilibrium conditions. The purification of the device state isExpand
Feedback control in quantum transport
Quantum transport is the study of the motion of electrons through nano-scale structures small enough that quantum effects are important. In this contribution I review recent theoretical proposals toExpand

How to include a delay between detection and control operation in the master equation theory of feedback-controlled quantum transport and how this formalism can be used to model finite detector bandwidth are described. Expand
A feedback scheme for control of single electron transport
We revise a feedback control scheme for single electron transport. It is based on the idea of an adaptive modulation of the system parameters (such as tunnel rates) during the observation of the fullExpand

A double quantum dot monitored by a nearby quantum point contact is considered, where the measurement-induced backaction plays an important role, and a simple feedback-control law is proposed to realize and stabilize the tunneling current. Expand
Current rectification in a double quantum dot through fermionic reservoir engineering
Reservoir engineering is a powerful tool for the robust generation of quantum states or transport properties. Using both a weak-coupling quantum master equation and the exact solution, we show thatExpand
Electronic Maxwell demon in the coherent strong-coupling regime
We consider a feedback control loop rectifying particle transport through a single quantum dot that is coupled to two electronic leads. While monitoring the occupation of the dot, we applyExpand
Strong suppression of shot noise in a feedback-controlled single-electron transistor.
The suppression of shot noise in a single-electron transistor is demonstrated using an exclusively electronic closed-loop feedback to monitor and adjust the counting statistics and with increasing feedback response the authors observe a stronger suppression and faster freezing of charge current fluctuations.
