Angled view scanning electron microscope image of the device gate structure. The blue overlay represents the electrically active part of the device. The upper left portion of the device serves as a charge sensor (CS) to detect the state of the qubit. Donors are implanted in the regions designated by the dashed red lines. The relevant donor (D) located next to the quantum dot (QD) is indicated by the red dot. Scale bar: 200 nanometers.
