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, an overview over different concepts of quantum imaging and sensing will be given with a particular focus on nonlinear interferometers that allow sensing in extreme wavelength ranges detecting visible light only. In addition, a brief excursion into quantum walks of photonic quantum states in waveguide lattices will be provided.
