German quantum technology company SAXON Q has developed a powerful quantum computer that operates without the need for specialized laboratories or large cryogenic cooling systems.
On July 21, the company commercially launched its SXQ128 and SXQ512 systems, offering 128 and 512 qubits, respectively. These are the first quantum computers using diamond nitrogen-vacancy (NV) center technology to surpass the 10-qubit threshold.
The new 100+ qubit systems support demanding applications such as quantum convolutional neural networks (QCNNs), advanced materials research, variational algorithms, and quantum chemistry simulations.
SAXON Q Solves Quantum Manufacturing Challenge
SAXON Q CEO Marius Grundmann said the key challenge in NV-center quantum computing is precisely manufacturing practical qubits. He said the company has now overcome that obstacle.
Grundmann added that the SXQ128 and SXQ512 operate like conventional computers, delivering reliable, continuous performance without requiring a team of specialists for maintenance.
Unlike most quantum computers, SAXON Q’s systems operate at room temperature using microscopic defects in synthetic diamonds instead of cryogenic cooling.
These nitrogen-vacancy (NV) centers let quantum processors control electron and nuclear spins without liquid helium cooling or high-vacuum conditions.
SAXON Q Boosts Diamond Qubit Manufacturing Efficiency
Producing diamond-based quantum processors has traditionally been highly inefficient, with industry manufacturing yields typically ranging from only 1% to 10%. SAXON Q’s sulfur co-implantation technique boosts qubit production efficiency above 85%, enabling reliable high-density fabrication.
The system achieves up to 99.92% fidelity, with fewer than one error per 1,000 operations, while maintaining long-lasting quantum coherence for complex applications.
SAXON Q is positioning its quantum systems as practical solutions for real-world applications. The machines fit into standard server racks and run on normal power requirements, without needing specialized cooling or environmental infrastructure.
Additionally, the technology offers six to ten times greater energy efficiency than power-intensive GPU clusters performing similar computational tasks.
SAXON Q’s multi-core operating system enables its quantum hardware to provide eight fully entangled qubits per core in the SXQ128 model and 16 per core in the SXQ512 version.
The platform scales, allowing organizations to start small and expand quantum computing capacity as needs grow.
The SXQ128 targets near-term quantum applications, while the SXQ512 adds modules and higher per-core performance. This increased capability allows it to support more complex scientific research and demanding industrial applications.
SAXON Q Systems Advance Real-World Industrial Applications
Previous generations of SAXON Q’s systems have already been installed at organizations including the German Aerospace Center and Fraunhofer IWU. Fraunhofer IWU’s SAXON Q system has operated continuously at room temperature since June 2025, supporting industrial optimization and exceeding fidelity targets.
The technology is backed by 220+ patents, supporting future 10,000-qubit systems and chip-scale quantum coprocessors.
Both models are now available for purchase. The SXQ128 will ship within three months, while the SXQ512 will begin deliveries in Q2 2027.
