Thermally driven quantum refrigerator autonomously resets superconducting qubit

Classical thermal machines are ubiquitous in the real world, but their quantum counterpart had so far been theoretical curiosities. Here, we build a quantum refrigerator that demonstrates for the first time an important real-world application—resetting of a qubit. Our quantum refrigerator—constituting of two superconducting qubits, each connected to a physical heat bath—autonomously cools down a target superconducting qubit to its ground state more effectively than conventional methods.
