Record-breaking photons at telecom wavelengths-on demand

A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons that combines on-demand operation with record-high photon quality in the telecommunications C-band-a key step toward scalable photonic quantum computation and quantum communication. "The lack of a high-quality on-demand C-band photon source has been a major problem in quantum optics laboratori...
