Abstract
A quantum device is described that includes a substrate with a layered structure, e.g. heterostructure, forming a quantum well layer. A doped region is connected to the layered structure for exchanging charge carriers with the quantum well layer. A patterned layer of electrically conductive material forms a set of gates including an accumulation gate. The accumulation gate comprises an accumulation pad configured to accumulate a two-dimensional charge carrier gas (2DCCG) in an active region of the quantum well layer connected there below to the doped region. At least part of an electric pathway between the accumulation pad and a connection pad is narrowed to form a nanoscale constriction for cutting off the active region of the quantum well layer.
