Scaling fault-tolerant superconducting quantum computers requires addressing the challenge of increased wiring, and microwave-to-optical quantum transducers offer a potential solution by enabling optical fiber links between dilution refrigerators. We are developing an ultra-low-power transducer utilizing diamond color centers in optomechanical cavities. In this presentation, we report the observation of the Purcell effect for color centers in a diamond optomechanical crystal integrated on an optical waveguide chip through fluorescence lifetime measurements.
