Claim 0:
1. An electronic device for storing, controlling and manipulating electron or hole spin based semiconductor qubits, the device comprising:
an electrically insulating layer with, on a front side, a front face, and on a back side, a back face,
on the front face of the insulating layer, a trapping structure for electrons or holes which includes:
a channel portion, at least partly formed by a layer portion of semiconductor material extending in a plane parallel to said electrically insulating layer, and
a plurality of gates distinct from one another, distributed in one or more levels on the channel portion, on a side of the channel portion opposite to said electrically insulating layer, the plurality of gates of the trapping structure being distributed along rows parallel to one another and

on the back side of the electrically insulating layer, an electric track which extends in a plane parallel to the electrically insulating layer, for generating an oscillating magnetic field exerted on said at least one electron or hole trapped in the trapping structure, the electric track including a plurality of portions, each parallel to said rows, and which are electrically connected in series one after the other to form meanders.
