N2 - 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. Using the NV spins as a local sensor, we find that the MSSW couples resonantly, and the NV spins amplitude grow linearly with the applied microwave power, suggesting that this approach could be extended to amplify the signal from neighboring spin qubits by several orders of magnitude.
