Delft-based Groove Quantum has secured 16 million euros in funding and unveiled an 18-qubit germanium spin-qubit processor, which it claims is the largest semiconductor-based quantum processor to date. The processor is designed as a modular building block, with a tiling architecture intended to scale toward larger systems without redesigning the core layout. The spinout from Qutech now targets 100 qubits, alongside plans to transition production to established semiconductor foundries.
Spun out of Qutech in 2024, Groove is betting on germanium spin qubits as a CMOS-compatible, scalable quantum architecture. Unlike superconducting systems pursued by IBM and Google, or trapped-ion approaches from IonQ, the company’s design targets a middle ground between control and density. Its qubits measure only a few hundred nanometers, enabling dense integration while remaining compatible with existing fabrication techniques.
The capital raised consists of 10 million euros in equity from a seed round led by Innovation Industries and 55 North, with additional backing from Verve Ventures and the European Innovation Council Fund. A further 6 million euros comes from public grants, including support under the EU Chips Act, underscoring continued alignment between quantum and semiconductor policy.
