Long-distance excitation of nitrogen-vacancy centers in diamond via surface spin waves
Long-distance excitation of nitrogen-vacancy centers in diamond via surface spin waves
We make use of room-temperature magnetostatic surface spin waves (MSSWs) to mediate the interaction between the microwave field from an antenna and the spin of nitrogen-vacancy (NV) centers in diamond. We show that this transport spans distances exceeding 3 mm, a manifestation of the MSSW robustness and large diffusion length. …
