Groove Quantum, a Delft-based quantum computing startup developing scalable germanium spin-qubit processors, has raised €16 million in combined funding and unveiled an 18-qubit semiconductor spin-qubit processor, which the company says is the largest of its kind ever built. The round includes €10 million in equity co-led by Innovation Industries and 55 North, with participation from Verve Ventures and the European Innovation Council Fund. The remaining €6 million comes through grants from the EIC Accelerator programme and the EU Chips Act funding programme. “Quantum computing will only have real impact if it can be engineered and manufactured at scale. With this funding and our 18-qubit prototype, we’ve shown that semiconductor spin qubits are not just a promising idea. They are ready to scale rapidly, and we believe our approach gives us the best shot at reaching the million-qubit systems that will change the world. “We are building technology to be produced and deployed at global commercial scale, just as every substantial semiconductor technology before us,” says Dr Anne-Marije Zwerver, CEO and Co-founder of Groove Quantum. A quick analysis of 2026 activity shows several comparable quantum and adjacent DeepTech funding announcements alongside Groove Quantum’s €16 million raise. - Delft-based Orange Quantum Systems / OrangeQS raised €15 million to scale quantum chip testing infrastructure, making it the most directly comparable example by both geography and sector, as it is also based in Delft, Netherlands. - Dublin-based Equal1 closed a €51 million round to scale silicon-based quantum computing - Espoo-based IQM Quantum Computers secured €50 million to support quantum technology development and market expansion. In adjacent quantum-enabling hardware: - Münster-based Pixel Photonics raised €13.5 million to accelerate market entry for superconducting single-photon detector technology - Lausanne-based Rhonexum raised €867.5k to advance cryogenic electronics for scalable quantum computing - Tampere-based Vexlum raised €10 million to
