Entanglement and quantum metrology with microcavities — •Jakob Reichel — Laboratoire Kastler Brossel (ENS-PSL, SU, CRNS, CdF) Paris

Entanglement is at the heart of quantum science and technology, and is a key resource for quantum-enhanced precision measurement. In cold-atom systems, photon-mediated interactions in optical cavities are a particularly attractive platform for generating high-fidelity entangled states in a scalable way. This relatively new approach is rapidly gaining importance, with important advances being achieved in the last few years. I will try to give an overview of the different ways in which cavities can be used to create and detect entanglement, and discuss some recent advances, showing where we are on the way to entanglement-enhanced metrology-grade clocks and sensors. One of the factors driving the progress in this field is the advancement of optical cavity technology, and I will also highlight the progress of the fiber Fabry-Perot microcavities used in the work in our group.
