Popis: The difficulty in obtaining a superconducting gap free of subgap states has hindered progress with hybrid superconductor-semiconductor devices in germanium. Here, this challenge is addressed by using a germanosilicide parent superconductor to contact high mobility planar germanium, facilitating scalable quantum information processing.
