Herr Dr. Sven Ramelow (Leiter der Emmy Noether-Nachwuchsgruppe "Nichtlineare Quantenoptik" am Institut für Physik der Humboldt-Universität zu Berlin) spricht zum Thema "Mid-Infrared Quantum Imaging and Spectroscopy".

Abstract: Mid infrared (mid-IR) light is technologically highly relevant but plagued with severe technological problems for real-world applications, because detectors and cameras, as well as bright enough light sources in the mid-IR have many orders of magnitude worse performance than their counterparts in the visible wavelength regime. Using quantum optics one can overcome these limitations by not requiring any detectors or any laser sources in the mid-IR, and instead only using visible light lasers and cameras. This is enabled by a recently introduced approach based on induced quantum coherence (INQC) imaging to realize “quantum imaging with undetected photons“ (Nature 512, 409, 2014, http://www.nature.com/nature/journal/v512/n7515/full/nature13586.html ). Implementing mid-IR quantum imaging and spectroscopy will not only open up an entirely new wavelength regime for single photon quantum optics but also be practically useful for applications in chemical sensing, biological analysis or medical diagnostics. Moreover, because the entire approach intrinsically relies on quantum entanglement it naturally provides avenues for quantum enhanced resolution and sub-shot-noise performance.
