| contents | We experimentally demonstrate coherent Rabi oscillations of Nitrogen Vacancy (NV) centers by magnetoelastic waves. The coupling is consistent with dipolar stray field drive from spin-wave modes in a ferromagnetic film, and displays a significant improvement in Radio Frequency power efficiency relative to other methods of microwave excitation. Further, it demonstrates coherent coupling with NV centers over mm-scale distances from the microwave excitation source. By utilizing a piezoelectric-magnetostrictive heterostucture, where magnetoelastic waves can be launched by an applied voltage, a pure voltage driven coherent drive of the NV centers is achieved. This voltage driven, magnetoelastic excitation enables a new approach to couple with two level quantum states that is not reliant on long spin-wave coherence lengths. |
