(a) Measurement setup for transport and charge sensing. (b) The upper right curve is the QPC conductance versus the QPC gate voltage while the cross indicates the highly sensitive position. The lower left one is the transport signal of the QPC versus gate voltage VM. (c) The upper curve represents the transport signal of the double quantum dots, and the lower one indicates the modulation signal of the QPC. The figure is from Ref. [53].
