Abstract
An electronic component with multiple quantum islands is provided, including a substrate on which rests a nanowire made of semiconductor material not intentionally doped; two main control gates resting on the nanowire so as to form respective qubits in the nanowire, the two main control gates being separated by a groove, and bottom and lateral faces of the groove are covered by a dielectric layer; an element made of conductive material formed on the dielectric layer in the groove; a carrier reservoir that is offset with respect to the nanowire, the element made of the conductive material being separated from the carrier reservoir by another dielectric layer such that the element made of the conductive material is coupled to the carrier reservoir by field effect. A method of fabricating an electronic component with multiple quantum islands is also provided.
