German startup Saxon Q has unveiled the world's first diamond-based quantum computing system exceeding 10 qubits that runs at room temperature and simply plugs into a standard wall outlet. The rack-mounted machine skips the bulky cryogenic cooling that conventional superconducting quantum computers require.
The system uses nitrogen-vacancy defects in synthetic diamond as qubits, with sulfur atoms co-implanted during fabrication to sharpen qubit control. Saxon Q's current lineup reaches 128 qubits, with 512-qubit versions due for delivery in 2027 and a longer-term goal of 10,000+ qubits after 2030. The company reported a 99.92% fidelity rate before error correction, with the latest single-qubit operations hitting 99.98% — figures comparable to results from IBM and MIT.
Because the hardware fits a standard server rack and needs no specialized cooling, Saxon Q is pitching it for edge-computing scenarios like autonomous driving and robotics, where sending data to a distant cloud quantum computer would be too slow.
