Scalable generation of heralded single photons via active feed-forward switching of a fiber delay line
Xavier Barcons Planas, Helen M. Chrzanowski, Janik Wolters
Quasi-deterministic single-photon generation is a key requirement for many photonic quantum technologies. Photon sources based on spontaneous parametric down-conversion (SPDC) are…

Pure narrowband photon-pair generation in a monolithic cavity
Xavier Barcons Planas, Helen M. Chrzanowski, Janik Wolters
Photonic quantum technologies require efficient sources of pure single photons. We present a heralded single-photon source based on spontaneous parametric down-conversion in a mono…

Polymer identification via undetected photons using a low footprint nonlinear interferometer
Atta Ur Rehman Sherwani, Emma Pearce, Philipp Hildenstein +5
Plastic pollution has become a critical global challenge, with microplastics pervading ecosystems and entering human food chains. Effectively monitoring this widespread contaminati…
