Abstract :
Recent advances in quantum optics and atomic physics have enabled experimenters to begin exploring realtime feedback in quantum settings. In addition to the practical significance of such work for fields like nanotechnology and quantum information processing, research on quantum feedback probes the fundamental physics of conditional evolution for observed systems. Feedback in quantum settings is generally complicated by the intricacies of ´wave-function collapse´ and measurement back-action, so that the proper design of quantum feedback controllers will require accurate quantitative models for the measurement process.
