Silicon-vacancy (SiV) color centers in diamond are promising candidates for enhancing quantum communication systems. SiVs exhibit advantageous characteristics as solid-state emitters with an effective optical interface and protective inversion symmetry. This setup enhances the entanglement generation between spin qubits and photonic qubits, which is a crucial step toward building scalable quantum communication networks. Key challenges in achieving coherent interactions between nuclear spins and SiV are ultra-low temperatures and strong currents that generate radio-frequency fields. Here, we present a platform integrating nuclear magnetic resonance coils with nanophotonic structures designed to operate at millikelvin temperatures, thus paving the way for advancements in quantum networks using SiV-based systems.
