In our approach, the electronic spin of a single nitrogen-vacancy impurity is employed to control the coherent coupling between the mechanical modes of two carbon nanotubes. We demonstrate that a mechanical phonon can be in a coherent superposition of wave and particle, thus exhibiting both behaviors at the same time. Furthermore, we discuss the mechanical noise tolerable in our proposal and predict a critical temperature below which the morphing between wave and particle states can be effectively observed in the presence of environment-induced fluctuations.", "revisions": [ { "version": "v1", "updated": "2018-07-09T14:35:16.000Z" } ], "analyses": { "keywords": [ "massive mechanical resonators", "macroscopic quantum delayed-choice experiment", "quantum wave-particle superposition", "single nitrogen-vacancy impurity", "electronic spin" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable" } } }
