Using Feedback to Increase Information About Quantum States

Speaker: Dr. Kurt Jacobs, Griffith UniversityAbstract: We consider using feedback control to increase the rate at which a continuous measurement extracts information about a quantum system. We show that there is a purely quantum effect which may be exploited to this end, as well as an essentially classical algorithm which involves directing the system to states which are well-distinguished by the measurement.Bio: Kurt Jacobs completed his masters degree under Dan Walls at the university of Auckland in 1995, and his PhD under Peter Knight at Imperial College in 1998. From there he went to Los Alamos National Laboratory where he spect three years as a postdoctoral research associate with Salman Habib. After that he worked in Paris for a year at a small supercomputing company doing numerical finance, and for the last 2 and half years has been a research fellow at the Griffith University, at the Center for Quantum Computer Technology, with Howard Wiseman. He is about to take up another postdoctoral position with Jonathan Dowling at LSU in Baton Rouge.Host: Professor Todd A. Brun, tbrun@usc.edu
