Nature: LaHaye and colleagues have taken an important step towards the observation of quantum phenomena in nearly macroscopic moving objects. They report experimental evidence of an intriguing interplay between a superconducting artificial atom and a micrometre-size mechanical resonator. Remarkably, their findings can be described using the ‘language’ of radiationâmatter interactions, which has also been successful in explaining the coupling of a superconducting artificial atom to microwave photon.
