    "body_text": "The researchers placed silicon nanocavities over shallow vanadium dopants in commercial 4H silicon carbide. They report Purcell-enhanced emission from ensembles, isolation of individual centers with high-purity single-photon emission and a 109-nanosecond enhanced lifetime. One lensed fiber handled the optical interface, including a 905-nanometer repump that recovered the vanadium charge state with 95% efficiency. The device is a preprint-stage platform demonstration, not a deployed quantum-network node.",
