Groove Quantum

The Dutch city of Delft has become one of the most important addresses in quantum computing, home to a cluster of academic and commercial organizations that have made it a European hub for the field. Groove Quantum is the latest company to emerge from that ecosystem, and it is focused on a technical approach that sets it apart from much of the industry: spin-qubit processors built from germanium. The choice of germanium is significant. Most quantum hardware today relies on materials and manufacturing processes that are far removed from the semiconductor industry's existing production infrastructure. Groove Quantum's germanium spin-qubit architecture is different — it is compatible with established CMOS manufacturing processes, which means the path from laboratory to industrial-scale production is shorter and more clearly defined than it would be for more exotic qubit technologies. That compatibility is not a minor footnote; it is a core part of the company's thesis about how quantum computing will actually scale. In 2026, Groove Quantum presented an 18-qubit processor — a milestone that represents meaningful progress toward the multi-qubit architectures that will eventually be needed for commercially relevant quantum computation. Qubit count alone does not tell the whole story, but the trajectory matters: each generation of processor is evidence that the underlying technology can be built upon, not just demonstrated in a lab. The company has raised €16 million in total, structured as €10 million in equity led by Innovation Industries and 55 North, plus €6 million in non-dilutive grants from the EIC Accelerator and the EU Chips Act. The grant component is a signal that European institutions recognize germanium spin-qubit technology as strategically relevant — not just as a scientific project but as potential industrial infrastructure for a sovereign European quantum capability. Groove Quantum is building toward that future one qubit at a time.
