Hong-Ou-Mandel effect with two frequency-entangled photons of vastly different color
Felix Mann, Helen M. Chrzanowski, Marlon Placke +2
In the original formulation of the Hong-Ou-Mandel (HOM) experiment, when two otherwise indistinguishable photons are incident upon the two input ports of a balanced beam splitter,…

Mid-IR hyperspectral imaging with undetected photons
Marlon Placke, Chiara Lindner, Felix Mann +5
Sensing with undetected photons has become a vibrant, application-driven research domain with a special focus on the mid-infrared (mid-IR) wavelength region. Since the mid-IR conta…

Noise analysis of a quasi-phase-matched quantum frequency converter and higher-order counter-propagating SPDC
Felix Mann, Helen M. Chrzanowski, Felipe Gewers +2
Quantum frequency conversion (QFC) will be an indispensable ingredient in future quantum technologies. For example, large-scale fibre-based quantum networks will require QFC to int…
