Quantum sensing of magnons with a superconducting qubit
TL;DR: In this paper, the magnetostatic mode of a ferrimagnetic crystal is coupled to a superconducting qubit for the detection of magnons using Ramsey interferometry with a sensitivity on the order of 10 − 3magnons/sqrt[Hz].

Single-photon quantum regime of artificial radiation pressure on a surface acoustic wave resonator
TL;DR: In this paper, the authors demonstrate an artificial realization of the radiation pressure of microwave photons acting on phonons in a surface acoustic wave resonator, which adds a key element to the quantum optomechanical toolbox and can be applied to quantum information interfaces between electromagnetic and mechanical degrees of freedom.

TL;DR: In this article , the authors used a flux-driven Josephson parametric amplifier (JPA) with the aim of approaching a noise level near the theoretically allowed limit of half quanta, and found the added noise to the system with a JPA as the first-stage amplifier to be lower than 110 mK at the frequencies from 0.938 GHz to 0.963 GHz.
