A quantum dot is laterally coupled to the conduction channel of a quantum point contact (QPC). The device was used to study how the conductance through a QPC is modified when the continuous energy state of a QPC is coupled to the discrete energy states of quantum dots. This work demonstrates that the Fano resonance is a possible candidate for the origin of the 0.7 conductance anomaly observed in QPCs.
