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 superconducting proximity effect on the surface state of a topological insulator is promising to generate topological superconductivity. Here, Yasuda et al. reported enhanced nonreciprocal charge transport in a Bi2Te3/FeTe heterostructure with an emerging superconducting order parameter.

    Continuous-variable remote state preparation in the microwave domain would allow to leverage the superconducting technology for quantum networks applications. Here, the authors show how to deterministically prepare squeezed Gaussian states across 35 cm using previously shared entanglement.

    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.

    A theoretical analysis of exotic superconductors suggests that it is possible to manipulate the state of their order parameter with light. This will help engineer devices from topological superconductors by patterning regions with different orders.

    Georg Bednorz, together with Karl Alexander Müller, discovered high-temperature superconductivity (HTS) in ceramics, for which they were awarded the Nobel Prize in Physics in 1987. Christine Horejs talks to Georg Bednorz about the successes and challenges of his research on HTS, applications of HTS materials, and the key ingredients for scientific discoveries.
