Topological qubit device

Abstract:

Devices, systems, and/or methods that can facilitate topological quantum computing are provided. According to an embodiment, a device can comprise a circuit layer formed on a wiring layer of the device and that comprises control components. The device can further comprise a topological qubit device formed on the circuit layer and that comprises a nanorod capable of hosting Majorana fermions and a quantum well tunable Josephson junction that is coupled to the control components.
