Silicon vacancy color center(SiV) in diamond, when combined with nanophotonic cavities, are a promising platform for network-based quantum solid-state processors. This is due to their spin transition being photonically addressable and a high noise tolerance. Pairing these processors with a fiber network can enable efficient long-distance quantum communication. It also presents a modular approach to building larger quantum processors. Here we present our experimental platform and first results.
