Exploiting the quantum properties of light offers new possibilities for quantum imaging and sensing. As such, one can harness entanglement, correlations, or quantum coherence of photon pairs to circumvent classical limitations in imaging and sensing. This includes super sensitive two-photon absorption, sub-shot noise ghost imaging, and imaging and sensing with undetected light. Besides fundamentals, a brief overview of different concepts of quantum imaging and sensing will be given, with a particular focus on nonlinear interferometers that allow imaging/sensing with undetected light.
