  • Analogous to the radiation-pressure coupling known in optomechanics, photon-pressure interaction between superconducting circuits can reach the strong coupling regime, which allows flexible control of the electromagnetic resonator’s quantum state.

  • Superconducting qubits are promising for quantum information processing, yet maintaining their coherence for long periods is hard. Bernon et al.characterize the coherence of cold atom superposition states trapped on superconducting atom chips and show that such long-lived ensembles are a viable alternative.

  • Microwave circuits are interesting tools for microwave optomechanics and quantum information processing. Here, the authors demonstrate a phase-sensitive microwave amplifier by using parametric frequency modulation of a MHz mechanical nanobeam integrated in a superconducting microwave cavity.

  • Nonlinear damping is a ubiquitous phenomenon in technological applications involving oscillators, but its origin is sometimes poorly understood. Here, the authors highlight how the interplay between quantum noise and Kerr anharmonicity introduces an effect resembling nonlinear damping.

  • Cavity optomechanics studies interactions between mechanical oscillators and the radiation pressure induced by intracavity photons. The authors embedded a nonlinear Josephson junction in their microwave cavity to make the cavity response highly nonlinear and observed a counter-intuitive optomechanical process, blue-tone mechanical cooling.
