Abstract
A spin Qbits quantum device includes a substrate of the semiconductor on insulator type provided with a surface semiconductor layer disposed on an insulating layer, the insulating layer being arranged on an upper face of a semiconductor support layer, and a component formed of one or more quantum islands extending in the surface layer and one or more gate electrodes for electrostatic control of the islands. Front gate electrodes are disposed on the surface layer, and the component includes a back electrostatic control gate formed of a conductive layer lining lateral walls and a bottom of an opening passing through the support layer from a lower face opposite the upper face up to the insulating layer. The conductive layer is disposed at the bottom of the opening in contact with the insulating layer, the conductive layer being disposed in contact with the support layer at the lateral walls.
