Many quantum technologies—such as cryptography, quantum computing and quantum networks—hinge on the use of single photons. While she was at the Kastler Brossel Laboratory (affiliated with the Pierre and Marie Curie University, École Normale Supérieure and CNRS) in Paris, France, Virginia d'Auria and her colleagues identified the extent to which photon detector characteristics shape the preparation of a photon source designed to reliably generate single photons. In a paper about to be published in European Physical Journal D, the French team determined the value of key source parameters that are necessary to generate high-fidelity single photons.
