Hole spin qubits in layered material. (IMAGE) Institute of Science and Technology Austria Caption The two holes are confined to the germanium-rich layer just a few nanometers thick. On top, the electrical gates are formed by individual wires with voltages applied. The positively charged holes feel the push and pull from the wires and can therefore be moved around within their layer.
