en.Wedoany.com Reported - German quantum computing startup SAXON Q has announced the launch of two commercial processors, the SXQ128 (128 qubits) and SXQ512 (512 qubits), marking the first time a quantum processor based on diamond nitrogen-vacancy (NV) centers has surpassed the threshold of 10 physical qubits. Spun out from Leipzig University, the system operates entirely at room temperature, requiring no cryogenic cooling, vacuum infrastructure, or specialized cleanroom facilities. These units are designed to slide directly into standard server racks, drawing power from standard AC outlets, while offering 6 to 10 times higher energy efficiency than GPU-based classical hardware clusters.
The primary engineering bottleneck for diamond NV center quantum computing has historically been low conversion yield—the percentage of implanted nitrogen atoms that successfully form stable, functional qubit centers within the diamond lattice. Traditional manufacturing techniques typically achieve only 1% to 10% conversion rates. SAXON Q has overcome this manufacturing limitation through a proprietary sulfur co-implantation process, protected by over 220 patents and applications. This technology achieves a conversion yield exceeding 85%, enabling precise, high-density placement of NV centers within the diamond substrate. The resulting NV qubits exhibit single-gate fidelity as high as 99.92%, meaning fewer than one error per 1,000 operations, sufficient to maintain state stability for running complex, multi-step algorithmic computations. The platform also introduces a multi-core quantum architecture operated by a proprietary QOS, with the SXQ128 providing 8 fully entangled qubits per processing core, while the SXQ512 expands capacity to 16 entangled qubits per core. The system is modularly upgradable by swapping diamond chips or adding processing cores.
SAXON Q's previous-generation room-temperature systems are already actively used by research institutions, including the German Aerospace Center (DLR) and the Fraunhofer Institute for Machine Tools and Forming Technology (IWU), through local deployment and cloud APIs for industrial materials processing and robotics optimization. These systems target near-term applications including quantum convolutional neural networks (QCNN), variational quantum algorithms, materials research, and quantum chemistry simulations. The SXQ128 is available for immediate ordering, with first customer deliveries scheduled within three months (late summer 2026). The SXQ512 is available for pre-order, with customer shipments beginning in the second quarter of 2027. Under the leadership of CEO Professor Marius Grundmann and CTO Professor Jan-Berend Meijer, SAXON Q plans to extend its multi-core architecture to data center coprocessors and a logical qubit error correction roadmap, targeting over 10,000 qubits.
