In my report, I will first show our recent study on the linear response of the driven three-level a superconducting flux quantum circuit (SFQC) to a weak probe field.When the bias magnetic flux is at the optimal point, the SFQC responds to the probe field like natural atomic systems with ladder-type transitions.However, when the bias magnetic flux deviates from the optimal point, the three-level SFQC has a cyclic transition, thus it responds to the probe field like a combination of natural atoms with ladder-type transitions and natural atoms wit.h-type transitions.In particular, we give detailed discussions on the conditions for realizing electromagnetically induced transparency and Autler-Townes splitting in three-level SFQCs.
