  • Although noise is typically detrimental to quantum devices, it can serve as a resource for quantum thermal machines. Here, the authors demonstrate a device based on a superconducting quantum circuit that leverages noise to function as either a quantum heat engine or a refrigerator.

  • Clock precision is thought to be fundamentally limited by entropy production in out-of-equilibrium systems. A theoretical work now introduces a quantum clock design where precision grows exponentially with dissipation.

  • Resetting qubits in a quantum computer requires significant hardware resources. Now, an experiment demonstrates an on-chip quantum refrigerator that uses a thermal gradient to reset a superconducting qubit more effectively than conventional methods.

  • Manipulating quantum information encoded in a bosonic mode requires sizeable and controllable nonlinearities, but superconducting devices’ strong nonlinearities are normally static. Here, the authors use a SNAIL to suppress static nonlinearities and use drive-dependent ones to reach universal control of a bosonic mode.

  • The emission of light from qubits in a superconducting circuit can be controlled in order to choose the direction of the photons’ propagation, which could be used to route information in quantum networks.

  • Investigating photosynthesis processes in biological samples is challenging due to their complex and disordered structure. Based on analog quantum simulations with superconducting quantum circuits, the authors show how the interplay of quantum coherence and environmental interactions affects energy transport.
