We focuse on a diamond color center as a quantum memory that serves as a quantum interface for quantum conversion of microwave photons into photons for communication. The interaction between mechanical waves and a color center can be enhanced by amplifying mechanical waves converted from microwaves by a piezoelectric material deposited on diamond in a resonator. The microwaves are converted into mechanical waves by a SAW resonator with a resonant frequency of 5.1 GHz, and the interaction between the microwaves and the NV center in diamond is observed.
