Abstract: A quantum component comprises: a substrate; two suspension electrodes; a plurality of gate electrodes arranged between the two suspension electrodes, the two suspension electrodes being raised relative to the gate electrodes; at least one nano-object element, in particular, a nanowire or a nanotube, suspended between the two suspension electrodes, the at least one nano-object element being placed above the gate electrodes, the electrodes of the quantum component comprising: a plurality of low frequency gate electrodes for defining electrostatic potentials in the nano-object element so as to enable at least two quantum dots to be formed in the nano-object element; at least one microwave gate electrode; and wherein at least one electrode comprises a magnetic material, preferably a ferromagnetic material, and is configured so as to apply an inhomogeneous magnetic field to the nano-object element over the spatial extent of the nano-object element.
