Color centers in wide-bandgap semiconductors have developed as promising candidates for solid-state quantum emitters. Current experimental setups often rely on complex and resource-intensive cryogenic systems to control individual color centers. To address this challenge, we propose a scalable approach to multiplex divacancy color centers in silicon carbide within a single cryostat. Our strategy involves integrating confocal microscopy and fiber array coupling to efficiently interface multiple color centers with our photonic quantum chips. By leveraging the unique properties of color centers, we aim to implement multiplexed spin-photon entanglement experiments at the interface. This advancement will pave the way for the realization of large-scale quantum networks and quantum communication protocols.
