SAXON Q Launches 128- and 512-Qubit Diamond Quantum Computers, Promising 6-10x Better Energy Efficiency
3 articles · Updated · HPCwire · Jul 21
Summary
128- and 512-qubit SXQ systems are now commercially available from SAXON Q, marking the first diamond NV-center quantum computers to exceed 10 qubits and run at room temperature.
No cryogenic cooling, vacuum equipment or specialized facilities are required: both machines fit in a standard server rack, plug into standard power and are designed for continuous operation without frequent recalibration.
85% conversion yield from SAXON Q’s sulfur co-implantation process underpins the scale-up, far above the 1-10% typical for NV-center creation; the company also cites up to 99.92% qubit fidelity.
SXQ128 is available now with delivery within three months, while SXQ512 orders are open for deliveries starting in Q2 2027; pricing is custom-built by customer requirements.
Two earlier-generation systems are already deployed at Germany’s DLR and Fraunhofer IWU, where SAXON Q says the platform is being used for industrial optimization and accessed on premises or via cloud API.
With 512 qubits now in a server rack, which industries will be the first to achieve true quantum advantage over classical computers?
By solving a 30-year diamond puzzle, has a German startup just leapfrogged the giants in the global quantum race?
128- and 512-Qubit Diamond Quantum Computers Launched by SAXON Q: Room-Temperature, Mobile, and Industry-Ready
Overview
SAXON Q has launched the SXQ128 and SXQ512, the world’s first commercially available diamond-based nitrogen-vacancy (NV) center quantum computers to surpass the 10-qubit threshold. This breakthrough marks a major leap in quantum computing, making practical, real-world applications possible in fields like chemistry and AI. A key advantage is their efficient room-temperature operation, which greatly reduces infrastructure and energy needs. The technology’s reliability was proven when SAXON Q’s 4-qubit system passed all DLR Quantum Computing Initiative tests, highlighting its readiness for industrial use and accelerating the adoption of quantum-enhanced solutions.
