In pursuing fault-tolerant superconducting quantum computers, the proliferation of wiring connections presents significant challenges regarding spatial constraints and thermal influx. To address these issues, there is a critical need for high-efficiency, low-noise, ultra-low power quantum transducers capable of replacing microwave wiring with optical fibers. However, practical implementation at the required performance levels remains under development. This study presents progress toward developing ultra-low power quantum transducers utilizing diamond color centers within optomechanical resonators.
