Description | We have analysed strong coupling of electromagnetic fields to atoms and other resonator systems that can help to control light-matter interactions and nonlinearities in these systems. We have shown that the back-action of a continuous quantum measurement process can be exploited in sensing and in optical cavity systems, providing tools for quantum engineering of small systems and future quantum technologies. The work has triggered several studies of cooperative phenomena for controlling cold atoms with proposals for sensing applications. |
Exploitation Route | The developed tools for the studies of light-matter interactions and continuous quantum measurement processes could be exploited in theoretical analysis of many-body quantum systems and, e.g., in design of quantum technologies for sensing and metrology. |
