The BMFTR-funded SPINNING project has successfully demonstrated that hybrid-integrable, scalable, and near-room-temperature solid-state quantum components represent a robust and energy-efficient alternative to established quantum computing hardware platforms. The developed spin qubits in diamond outperform comparable commercially available superconducting systems in terms of longer operation times and lower error rates. Photonic coupling over distances of more than 20 meters promises to serve as a foundation for more powerful distributed quantum computers.
