Superconducting devices

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.

    The superconductor–insulator phase transition is a quantum phenomenon that reveals a competition between the superconducting phase order and charge localization. Now, microwave spectroscopy is shown to be a promising approach to investigate this effect in controllable one-dimensional Josephson arrays.
