In our work, we develop a reliable process to fabricate compact multi-electrode circuits that can sustain the harsh conditions of the nanotube growth. We measure high quality charge stability diagrams for double-quantum dots which may be coupled to the mechanical motion of the nanotube. We also discuss the read-out scheme for the future qubit.
