- A long-standing prediction for nanomechanical resonators is that they may behave as an effective acoustic laser if coupled to a two-level system: the mechanical mode serves as a cavity, while the two-level system acts as the lasing medium. This prediction remained untested because it required an unattainable combination of coupling strength and measurement speed. Our experiment achieved both requirements, allowing us to connect the physics of backaction with the physics of lasers, with applications to nanomechanics, quantum measurement, and quantum optics. This article was covered in Nature Reviews Materials, 2019.
