Abstract

Nitrogen-vacancy (NV) centers in diamond provide a platform for room temperature spin manipulation, making them a strong candidate for inclusion in optical levitation experiments seeking to couple mechanical and spin degrees of freedom. Here, we report progress on the coherent manipulation of single NV center spins contained within optically levitated nanodiamond in a free-space optical dipole trap. The NV center spin is coherently manipulated at both atmospheric pressure and low vacuum, and while the trapping beam causes a reduction in the fluorescence emitted by the center, no reduction in the spin coherence is observed. Further, after an initial exposure to low vacuum, the nanodiamond remains at near room temperatures at all pressures and trapping powers considered in these experiments.
