Germanium material with superconducting properties is used to open up new pathways for the development of scalable quantum devices.

An international research team published a paper in the latest Nature Nanotechnology, stating that they have prepared superconducting germanium material, which can conduct electricity in a zero-resistance state, allowing the current to flow continuously without loss. Achieving superconductivity in germanium opens up a new path for developing scalable quantum devices based on existing mature semiconductor processes.
