Single-shot coherent process tomography and mid-infrared polarimetry with undetected photons

Marthe Zeja, Wen-Zhe Yan, Zhibo Hou +1

Measurements with undetected photons infer properties of a probe beam that is never detected, transferring mid-infrared information onto silicon-friendly wavelengths. Tomography in…

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…

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,…

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…

Telecom-Band SPDC in AlGaAs-on-Insulator Waveguides

Marlon Placke, Jan Schlegel, Felix Mann +5

Widespread commercial adoption of telecom-band quantum-key-distribution (QKD) will require fully integrated, room-temperature transmitters. Implementing highly efficient spontaneou…

Low-noise quantum frequency conversion in a monolithic cavity with bulk periodically poled potassium titanyl phosphate

Felix Mann, Helen M. Chrzanowski, Felipe Gewers +2

Interfacing the different building blocks of a future large scale quantum network will demand efficient and noiseless frequency conversion of quantum light. Nitrogen-vacancy (NV) c…
