Their optically-active spins facilitate strong light-matter interactions for distributed quantum computing and enable atomic-scale resolution for cutting-edge biological sensing tasks. However, traditional NV spectroscopy relies on a meter-scale setup to control a single NV centre, limiting its scalability. Our research overcomes the challenge by combining NV centres with photonic and electronic integrated circuits built by commercial CMOS technologies. In this presentation, I will first outline our approach to heterogeneously integrating NV centres in nanodiamonds with foundry-fabricated silicon-nitride photonics. Next, I will discuss our recent advancements in reducing microwave crosstalk between densely-packaged spin systems using multi-layer microelectronics. Finally, I will demonstrate how our large-scale NV system can enable exciting applications in life sciences and foundational quantum research. Place：F104, Gongguan Campus, NTNU |
