Quantized fields for optimal control in the strong coupling regime — •Frieder Lindel1, Edoardo Carnio1, Stefan Yoshi Buhmann2, and Andreas Buchleitner1 — 1University of Freiburg, Germany — 2University of Kassel, Germany
The control of quantum systems lies at the core of many quantum technologies. In the field of coherent control, classical fields coherently drive the quantum system from a given initial state into a target state. Exploiting the quantum nature of the field to improve these control protocols has so far been mostly limited to the weak coupling regime. Here we will discuss how the quantum statistics of a bosonic field can be optimally tailored in order to drive a weakly or (ultra-)strongly coupled quantum system, such as an atom or a molecule in a cavity, towards a desired target state. This extends optimal control theory to control and target systems that are both quantized and strongly coupled.
