German company SAXON Q has built a high-powered “quantum computer” that doesn’t need a lab or giant supercoolers to run.
On July 21, the company announced the commercial launch of its SXQ128 and SXQ512 systems, scaling up to 128 and 512 qubits, respectively. These are the first quantum computers based on diamond nitrogen-vacancy (NV) centers to break past the 10-qubit mark.
Target workloads for the new 100+ qubit systems include quantum convolutional neural networks (QCNN), complex material research, variational algorithms, and quantum chemistry simulations.
“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,” Grundmann added.
Room-temperature operation
Quantum computers mostly depend on massive, freezing dilution refrigerators. But SAXON Q operates entirely at room temperature by leveraging microscopic defects in synthetic diamonds.
Known as nitrogen-vacancy centers, these atomic-scale structures allow the system to manipulate electron and nuclear spins without needing liquid helium or high-vacuum environments.
Typically, manufacturing these diamond processors has been inefficient, with industry conversion yields hovering around a dismal one percent to 10 percent. SAXON Q overcame this challenge using a patented sulfur co-implantation process. That trick bumped the qubit creation yield above 85 percent for predictable, high-density manufacturing.
This is not all. With fidelity touching 99.92 percent, the system averages fewer than one error per 1,000 operations. Notably, the stability keeps quantum states intact long enough to run demanding, real-world tasks without degradation.
With these quantum systems, SAXON Q is pitching real-world practicality. The systems sit in standard server racks, drawing routine power with no specialized environmental controls required.
Moreover, the tech demonstrates 6x to 10x better energy performance compared to energy-hungry GPU clusters running equivalent workloads.
Target workloads
Powered by a multi-core operating system, SAXON Q’s hardware delivers eight fully entangled qubits per core on the SXQ128 and 16 per core on the SXQ512.
The tech is also built with modularity in mind. For instance, companies can begin with a smaller setup and eventually boost quantum capabilities as the computing demands grow.
The SXQ128 is designed for near-term tasks like variational algorithms and quantum chemistry simulations. On the other hand, the SXQ512 expands on this architecture with additional modules and higher per-core capacity. This boosted power allows the SXQ512 to tackle a broader, more complex range of advanced research and heavy industrial workloads.
Earlier iterations of SAXON Q’s hardware are already deployed at institutions like the German Aerospace Center (DLR) and Fraunhofer IWU.
“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.”
Moreover, the company’s technology is protected by over 220 patents and pending applications, setting up a clear roadmap toward 10,000-qubit architectures and eventual chip-scale coprocessors.
Orders are live for both models. Customers can expect SXQ128 deliveries within three months, while the higher-capacity SXQ512 will start shipping in the second quarter of 2027.
