Abstract: We proposed a scheme to implement a self-contained quantum refrigerator system composed of three rf-SQUID qubits, or rather, flux-biased phase qubits. The three qubits play the roles of the target, the refrigerator and the heat engine respectively. We provide the three qubits with different effective temperatures, by imposing external current noises of different strengths. The differences of effective temperatures drives the refrigerator to cool down the target.
