Schematic illustration of the quantum refrigerator in a superconducting quantum circuit.

Caption

Two microwave channels act as hot and cold heat reservoirs, highlighted by a reddish and a bluish glow, respectively. The heat reservoirs are coupled to an artificial molecule consisting of two qubits. Controlled microwave noise (white arrows) is injected through the side ports to drive and regulate heat transport.
