The realization of Fault-Tolerant Superconducting Quantum Computer requires more than one million qubits, but the associated increase in microwave interconnects is a major challenge to be solved in terms of scalability and heat influx. Quantum Transducers, which convert microwave signals into optical photons, offer a viable solution to this problem. Such transducers are being developed using Diamond Optomechanical Crystals (Diamond OMCs) with embedded Nitrogen-Vacancy (NV) Centers, where efficient coupling to a photonic waveguide is critical for performance. We report a high-precision method to place a diamond crystal on a SiN waveguide using a tungsten probe. Optical characterization via a coupled fiber confirms the successful integration, as the photoluminescence spectrum shows both the NV center's zero-phonon line and a distinct cavity resonance peak. This achievement demonstrates reproducible optical access to the NV centers within the diamond OMC via the waveguide, marking a significant advance toward the construction of efficient and scalable quantum transducers. |
