Superconducting devices articles from across Nature Portfolio

Superconducting devices are electronic devices that harness the zero-resistance properties of superconductors. Superconducting devices are used for highly sensitive optical sensors, detectors of magnetic fields and low-noise amplifiers. Superconducting circuits are one possible type of qubit, the building blocks of quantum computers.

    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.
