Toward scaling up superconducting quantum processors, low-power and highly efficient microwave-to-optical (MW–optical) transducers are required. As part of our development of color-center-based transducers, we integrated a thin lithium niobate (LN) film on a diamond nanobeam and observed coupling between piezoelectrically driven mechanical modes and a single SiV center. By performing excitation fluorescence measurements of the sideband-modulated optical transition of the SiV center, we successfully detected multiple mechanical modes.
