Feedback control is the process
of monitoring a system and using the information, as it is being
obtained (that is, in real-time) to apply forces to the system to
control it's behavior. Generally the objective is to get the system to
maintain a desired evolution in the presence of noise or other
uncertainties. The subject of feedback control in classical systems is
well-developed, and feedback control is essential in many electrical
and mechanical devices. The application of feedback control
to
quantum systems is the subject of quantum feedback control.
A short review for a general physics audience is given in:
Quantum Feedback Control: How can we control
quantum systems without disturbing them?
