Key Ingredient: Change in Material Boosts Prospects of Ultrafast Single-photon Detector

Caption

Colorized micrograph of an ultrafast single-photon detector made of superconducting nanowires. NIST researchers use electron beam lithography to pattern the nanowires (vertical lines) on a thin film of tungsten-silicon alloy, which produces more reliable signals than the niobium nitride material used previously.
