Change in Material Boosts Prospects of Ultrafast Single-Photon Detector

PhysOrg.com reports that the use of tungsten instead of niobium nitride dramatically increases the speed of a single photon detector.

The market news is quoted as saying,

By swapping one superconducting material for another, researchers at the National Institute of Standards and Technology (NIST) have found a practical way to boost the efficiency of the world’s fastest single-photon detector, while also extending light sensitivity to longer wavelengths. The new tungsten-silicon alloy could make the ultrafast detectors more practical for use in quantum communications and computing systems, experiments testing the nature of reality, and emerging applications such as remote sensing.
