A quantum computing startup based in Delft has raised €16 million to develop scalable processors using germanium spin-qubit technology. Groove Quantum unveiled its latest processor with 18 qubits, claiming it is the largest of its kind ever built. The funding round was co-led by Innovation Industries and 55 North, with additional investors joining the round. The company now aims to accelerate production of chips that could outperform traditional silicon in quantum applications.
Groove Quantum specializes in germanium spin-qubit processors, a technology that uses the spin of electrons in germanium atoms to encode quantum information. This approach differs from the more common superconducting qubits or trapped ions used by other quantum companies. The 18-qubit processor represents a milestone in scaling up quantum chips, which are essential for building practical quantum computers.
The €10 million equity portion of the funding was led by Innovation Industries and 55 North, two investment firms focused on deep-tech startups. The remaining €6 million comes from grants and non-equity contributions. The company plans to use the funds to expand its team, refine manufacturing processes, and develop larger processors.
Challenges remain in achieving fault-tolerant quantum computing, but Groove Quantum’s approach targets higher stability and lower error rates compared to existing methods. If successful, this could position the Netherlands at the forefront of Europe’s quantum computing race. The startup’s next goal is to demonstrate a 50-qubit processor within two years.
Investors see potential in Groove Quantum’s technology due to its compatibility with existing semiconductor fabrication methods. This could reduce production costs and speed up commercialization compared to competitors relying on exotic materials or cryogenic systems.
