SAXON Q Launches 100+ Qubit Diamond-Based Room-Temperature Quantum Computers
German startup SAXON Q has moved beyond theoretical research by launching the first commercial diamond-based quantum processors capable of operating at room temperature. The company released the SXQ128 and the SXQ512 models, which provide 128 and 512 qubits respectively. This development marks a shift for the industry because these units do not require the massive cryogenic cooling systems or vacuum chambers that have long constrained quantum hardware. Instead, these processors fit into standard server racks and run on standard power outlets.
The hardware achieves this performance through a proprietary sulfur co-implantation process. Traditional diamond-based quantum manufacturing often struggles with low conversion yields of nitrogen atoms, typically ranging from one to ten percent. SAXON Q reports that its patented method pushes these yields above 85 percent. This allows for high-density qubit placement and single-gate fidelities reaching 99.92 percent. Because the system maintains stable states at room temperature, it functions with six to ten times the energy efficiency of classical hardware clusters using GPUs.
SAXON Q has already established a presence in the German research sector. Systems are currently deployed at the German Aerospace Center and the Fraunhofer Institute for Machine Tools and Forming Technology. These institutions use the hardware for material processing, robotics calculations, and chemistry simulations. The multi-core architecture allows for modular upgrades, where users can swap out chips or add processing cores to increase power.
Orders for the SXQ128 are open now, with shipments expected within three months. The larger SXQ512 unit is available for advance purchase with a delivery window starting in the second quarter of 2027. Leadership at the Leipzig University spinoff aims to scale this architecture toward data-center integration and future roadmaps targeting 10,000 physical qubits for error correction.
