Patent number: 12082512Abstract: A semiconductor-superconductor hybrid device comprises a semiconductor layer and a superconductor layer. The superconductor layer is arranged over an edge of the semiconductor layer so as to enable energy level hybridisation between the semiconductor layer and the superconductor layer. The semiconductor layer is arranged in a sandwich structure between first and second insulating layers, each insulating layer being in contact with a respective opposed face of the semiconductor layer. This configuration may allow for good control over the geometry of the semiconductor layer and may improve tolerance to manufacturing variations. The device may be useful in a quantum computer. Also provided is a method of manufacturing the device, and a method of inducing topological behaviour in the device.Type: GrantFiled: October 24, 2019Date of Patent: September 3, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Georg Wolfgang Winkler, Roman Mykolayovych Lutchyn, Leonardus Petrus Kouwenhoven, Farhad Karimi
