Abstract:
Observing and controlling macroscopic quantum systems has long been a driving force in research on quantum physics. The angular degrees of freedom of levitating diamonds coupled to embedded Nitrogen-Vacancy (NV) centers offer bright prospects towards this purpose. Indeed, using nanodiamonds trapped under low vacuum levels, the inherent quantum nature of the NV spin can in principle be transferred on to its mechanical motion.
I will present our demonstrations of coherent manipulations of the spin of NV centers [1] and of the spin-dependent torque and spin-cooling of the angular motion of diamonds levitating in a Paul trap [2]. I will also discuss our more recent demonstration of detection of dipolar interactions between NVs and of the full magneto-optical alignment of the diamond axes along the magnetic field using this spin-mechanical platform.
