Normal room temperature and abandoning complex extreme cooling
In an unprecedented scientific, engineering, and commercial move that could redraw the future of advanced computing and shift the balance of power in the tech world, a promising German startup known as SaxonQ, specializing precisely in advanced quantum technology and solutions, has announced the official and immediate commercial availability of its modern computer systems known by the code names SXQ128 and SXQ512. These advanced and powerful systems are quantum computers built primarily on cutting-edge technology using synthetic diamond chips with staggering processing capacities of 128 qubits and 512 qubits respectively for the two announced versions. These devices feature a unique and unprecedented technical and physical ability to operate entirely, efficiently, and with complete stability at normal ambient room temperature typical of office environments. This bold achievement represents a massive technological leap compared to the company’s previous limited machines and experiments, which were restricted to the limited 10-qubit category, successfully crossing the engineering-complex 100-qubit barrier for the first time using innovative and advanced nitrogen-vacancy center technology.

Advanced technical claims and commercial availability in markets
In stark and clear contrast to most current and well-known quantum computers developed by giant tech companies with open budgets such as IBM and Google—which inevitably and mandatorily require massive, expensive, and excessively power-consuming dilution refrigerators operating at harsh temperatures approaching absolute zero to ensure the stability of fragile computational operations and prevent environmental and thermal noise—the new German company’s systems use advanced synthetic diamond chips equipped with engineered and microscopic nitrogen-vacancy centers to form the solid, stable foundational platform for qubit operation. Thanks to this innovative and flexible engineering design, these compact computing units can be seamlessly placed inside standard server racks commonly used in traditional enterprise data centers, drawing the necessary operating power from standard available AC power outlets. This achieves very high and ideal electrical consumption efficiency that exceeds classical GPU-based device clusters by a factor of 6 to 10 times, according to the producing company’s claims and statistics.
It is worth noting in this technical context that this ambitious company, which originated as a spin-off from the venerable Leipzig University laboratories in Germany, had previously showcased a dual-core 10-qubit system at the prominent Hannover Messe industrial and technology trade fair in April 2026. The same company also previously, in a pioneering and experimental step, deployed and tested a small, portable 4-qubit quantum computer at the Fraunhofer Institute for Machine Tools and Forming Technology facilities in Dresden, Germany, in June 2025. The prestigious German Aerospace Center (DLR) is among the established entities already utilizing the company’s previous and older generation of systems in its scientific and advanced research.
According to reports by the specialized quantum news media platform The Quantum Insider, these modern and complex systems are fully compatible and easily integrated with standard open-source quantum programming software and development tools such as Qiskit and OpenQASM. These powerful quantum computers target operational capabilities for highly advanced scientific and commercial applications in areas such as quantum convolutional neural networks for AI development, variational quantum algorithms for optimization and problem-solving, complex materials research, the development and design of new molecules, and accurate quantum chemistry simulations that remain intractable for classical devices. Scientific reports have indicated that intensive and controlled laboratory tests demonstrated an operational logical gate fidelity reaching 99.92 percent, a very promising figure in this delicate technical field plagued by calculation errors.
General scientific context and anticipated future challenges
From a commercial, marketing, and practical standpoint, the advanced and fast SXQ128 system is available for immediate purchase orders now for interested organizations and institutions, with the company and its management expecting customer delivery and installation operations to begin within a maximum of just three months. As for the larger and more powerful SXQ512 system, it is currently available for pre-orders and registration only, with shipments to early buyers scheduled to begin during the second quarter of 2027.
This sudden and bold announcement by the company represents a massive and unprecedented technological claim in rapid computer scaling, jumping processing capacity from just 10 qubits to 128 qubits in a single commercial release available to the public and enterprises. The idea of room-temperature nitrogen-vacancy center-based quantum computing has long been viewed as a very promising, futuristic, and economical technology, but it was surrounded and constrained by extremely difficult technical and physical limits and obstacles, such as short coherence times and highly complex engineering challenges in scaling multi-qubit entanglement stably and effectively for long operations. Up to this point, no comprehensive results or reports from independent third parties have been published or announced regarding the actual benchmark and test performance of these new systems to confirm the claims, nor has the company transparently and detailedly disclosed the numbers of error-corrected logical qubits inside the software system or detailed physical coherence metrics beyond the single cited gate fidelity figure taken out of context, leaving the door wide open to some scientific questions regarding ultimate efficiency and operational reliability in complex applications.
