Summary
Saxon Q said its rack-mounted diamond quantum computers are now available with up to 128 qubits, marking what it calls the first nitrogen-vacancy system to exceed the 10-qubit threshold.
Sulfur co-implantation enabled the jump past 10 qubits by stabilizing negatively charged nitrogen-vacancy defects in synthetic diamonds, the company said, making the qubits easier to create and control.
Single-qubit fidelity reached 99.92% before error correction, with co-founder Marius Grundmann citing 99.98% in more recent July 22 results that were not independently verified.
The room-temperature machines fit standard server racks and plug into AC power, a potential edge for on-site uses such as robotics or autonomous driving where cloud latency is a drawback.
Saxon Q plans 512-qubit deliveries next year and targets 10,000 qubits after 2030, though chip size and scaling beyond current 8- or 16-qubit arrays remain major hurdles.
