Single-photon detectors

Scaling up single-photon detector arrays

Superconducting nanowire single-photon detectors offer outstanding performance, but the development of large-format imaging arrays is challenging. A new approach based on sectioning a single nanowire enables an eightfold improvement of the spatial resolution and the realization of a 1,024-pixel imager.
