Q 61.1: Invited Talk

Friday, March 10, 2023, 11:00–11:30, E001

Quantum Imaging With Nonlinear Interferometers — •Markus Gräfe — Institute of Applied Physics, Technical University of Darmstadt, Hochschulstraße 6, 64289 Darmstadt, Germany — Fraunhofer Institute for Applied Optics and Precision Engineering IOF, Albert-Einstein-Str. 7, 07745 Jena, Germany

Exploiting nonclassical state of light allows new imaging and sensing approaches. In particular, nonlinear interferometers enable quantum imaging with undetected light. Here, based on the effect of induced coherence, samples can be probed with light that is not detected at all. Instead, it quantum correlated partner light is is recorded and yields the information of the sample although it never interacted with it. The talk will outline the fundamental concept, recent progress and limits as well as perspectives for biomedical application.
