SAXON Q Launches Commercial Diamond-Based NV

Insider Brief - SAXON Q announced commercial availability of its SXQ128 and SXQ512 diamond-based NV-center quantum computing systems, which operate at room temperature without cryogenic cooling or vacuum infrastructure. - The systems use SAXON Q’s diamond manufacturing and multi-core architecture to support quantum workloads including chemistry simulations, optimization, and quantum machine learning. - The company says its NV-center platform is designed for scalable quantum computing deployments, with current systems available for order and future expansion toward larger architectures. Press release – SAXON Q, a pioneer in diamond-based nitrogen-vacancy (NV) quantum computing, today announces the commercial availability of the 128-qubit SXQ128 and 512-qubit SXQ512 — the first diamond-based NV-center quantum computers to ever exceed 10 qubits. Both systems operate at room temperature with no cryogenic cooling, vacuum equipment or specialized facilities required, offering organizations the ability to run quantum convolutional neural networks (QCNN) and chemistry simulations, accelerate materials research and develop the quantum workflows that will define the next era of computing. Built on semiconductor-compatible manufacturing processes and protected by more than 220 patents and pending applications, SAXON Q’s systems fit within a standard server rack, plug into a standard electrical unit and run continuously without the recalibration cycles or environmental controls that quantum computing has historically required. The systems are also significantly more energy efficient than GPU-based approaches — consistently demonstrating 6-10x better energy performance — further reducing the operational cost of deployment. “For thirty years, NV-center quantum computing was a question of manufacturing — whether we could place qubits with enough precision and yield to build something that works outside a laboratory. We solved that problem,” said Marius Grundmann, co-founder and CEO of SAXON Q. “The SXQ128 and SXQ512 are quantum computers that operate the way a computer should: reliably, continuously and without a team of specialists to keep it running.” The SXQ128 supports near-term quantum workloads including variational algorithms, quantum chemistry simulations and quantum amplitude estimation. The SXQ512 builds on the same architecture, significantly expanding computational capability through additional NV-center modules and increased per-core quantum capacity — broadening the range of problems addressable and making it well-suited to more demanding research and applied computing workloads. Two previous generation SAXON Q systems are currently deployed and in active use at the German Aerospace Center (DLR) and Fraunhofer IWU, where researchers access them on premises or via cloud API. “We began using a Saxon Q mobile quantum computing system in June 2025 for industrial optimization in material processing and robotics,” said Albrecht Hänel, Head of Digital Production Twin, Fraunhofer IWU. “The system has operated at room temperature continuously since installation — and has exceeded the gate fidelity specifications we outlined in the tender.” While traditional NV-center creation methods typically achieve conversion yields — the rate at which implanted atoms successfully become functional quantum bits — in the range of 1-10%, SAXON Q’s proprietary sulfur co-implantation process achieves greater than 85%, solving one of the fundamental challenges in scaling quantum computing systems. The resulting qubits achieve up to 99.92% fidelity — fewer than one error per 1,000 operations, and quantum states are stable long enough to run complex, real-world calculations without degradation. The SAXON Q platform is also the only commercially available NV-center quantum computing system capable of coordinating computation across multiple quantum processing cores simultaneously. Through its proprietary multi-core quantum operating system, the SXQ128 offers eight fully entangled qubits per core, while the SXQ512 features 16 per core. Both units are modular by design, giving organizations the ability to start with the SXQ128 and expand their quantum capability over time by simply upgrading the diamond chip or adding additional cores, providing a flexible entry point into quantum computing that grows alongside their needs. Error correction capabilities and logical qubit architectures are part of SAXON Q’s development roadmap, as the platform scales toward systems of 10,000 qubits and beyond. SAXON Q’s broader product roadmap extends to data-center-ready quantum co-processors and, ultimately, chip-scale quantum processors designed for embedded and mass-market deployment. SAXON Q was founded by researchers and executives whose credentials span decades of quantum science and commercial technology leadership. Prof. Dr. Marius Grundmann, co-founder and CEO, is Professor of Experimental Physics at Leipzig University, with nearly 700 peer-reviewed publications and 40 years in semiconductor physics. Prof. Dr. Jan-Berend Meijer, co-founder and CTO, is one of the world’s leading authorities on ion beam implantation — the process at the core of SAXON Q’s NV-center technology. Dr. Frank Schlichting, CEO, brings more than 30 years of executive experience across semiconductors, automotive and energy sectors.
