Continuous time limit of repeated quantum observations — •Bernhard Neukirchen — Leibniz Universität Hannover, Institute of Theoretical Physics, Germany

We look at the continuous time evolution of open quantum systems in the Markovian approximation. The goal is to describe all the information we can obtain about the System by measurements of the environment.

Since this problem is very well understood for discrete time, we set up the continuous time description as a refinement limit of the discrete approach in the step length. This construction can be used to obtain a full quantum description of the field emitted by a driven isolated system, e.g. a cavity or quantum dot.
