Spin-Phonon Coupling in Diamond Resonators
High quality factor single crystal diamond mechanical resonators provide a controlled platform for introducing strain to native NV centers. An optimized resonator geometry allows the NV’s electronic spin to coherently couple to the spatially extended phonon modes of the resonator through lattice strain. This coupling can be used for long-range spin-spin interactions and quantum optomechanical control of the resonator.
