Groove Quantum, a spin-out of the Delft University of Technology (TU Delft), has reported a key technological milestone together with a big funding infusion, marking a major shift in the worldwide race for quantum technology. In addition to receiving €16 million ($18.7 million USD) in total equity and grants to expand its operations, the business successfully unveiled an 18-qubit semiconductor spin-qubit processor, which is now the largest of its kind in the world.
Verve Ventures and the European Innovation Council (EIC) Fund are also involved in the fundraising package, which includes a €10 million initial round co-led by Innovation Industries and 55 North. €6 million in funds from the JU Chips Act funding programs and the EIC Accelerator support this equity investment. These monies are intended to help the company go from the experimental stage to commercial-scale engineering by increasing its quantum systems and overall operational capability.

The Germanium Advantage
Superconducting circuits and trapped ion structures have long dominated the field of quantum computing, but Groove Quantum is placing its bets on germanium. The company’s leadership feels this material is ideal for large production and scaling.
Groove Quantum co-founder and CEO Anne-Marije Zwerver said, “The future is built on germanium.” Germanium has better spin coherence than silicon, which is essential for computing with fragile quantum information. Additionally, germanium qubits may be easily integrated into current semiconductor production methods and have a modest footprint.
Importantly, the 18-qubit device was created utilizing a platform that is still compatible with conventional CMOS processes, which are the same methods utilized in the production of contemporary CPUs and GPUs. According to Groove Quantum, this interoperability will enable them to avoid the requirement for completely new, unaffordable manufacturing facilities, which have been a major obstacle to entrance for other quantum technologies.

A Lean Team with Massive Results
The efficiency with which Groove Quantum was developed is among its most remarkable features. In barely two years, a surprisingly small team of just eleven individuals constructed the 18-qubit processor. Zwerver observed that attaining such outcomes necessitated a high level of capital efficiency and “stubborn optimism,” joking that the small team successfully obtained degrees in several disciplines outside of physics to complete the job.
Lieven Vandersypen, Menno Veldhorst, and Giordano Scappucci, three pioneers in the field of semiconductor spin qubits, form a foundational group of advisers that support this project. While Veldhorst is credited with developing cutting-edge germanium quantum devices, Vandersypen’s team was the first to manipulate a single electron spin in a quantum dot and execute quantum algorithms on spin qubits. Groove Quantum has been able to gain substantial intellectual property, including multiple patent filings pertaining to qubit performance, yield, and scalability, because to this extensive academic background.

The Roadmap to Millions of Qubits
The introduction of the 18-qubit processor is a proof of concept for a scalable design, not just a ploy for a headline that would smash records. The corporation wants to switch from an 18-qubit gadget to a 100-qubit “unit cell” as soon as possible.
Like modern memory chips, this unit cell is made to be tiled. Groove Quantum thinks that by tiling these cells, they will be able to reach the millions of qubits required for real-world uses in industries like materials research, energy, and medicine.
This scaling is already supported technically. In 2024, the business achieved a record-breaking two-qubit gate fidelity of over 99% and showed a new low-power qubit control mechanism in a 10-dot array. Furthermore, single-qubit gate fidelities of 99.99% have been reported. For mistake correction and carrying out the intricate computations that will eventually enable quantum computers to surpass classical machines, high fidelity is essential.

Market Implications
Groove Quantum is already at the forefront of the semiconductor spin-qubit industry with a successful investment round and technical debut. The startup wants to “unlock the full potential of quantum computing” while lowering scaling expenses by utilizing current industrial methods.
The JU Chips Act and support from significant European investors highlight how strategically important it is to establish a strong supply chain for quantum hardware in Europe. The industry will be closely monitoring to see if the “germanium bet” pays off as the company uses its new funding to build its systems, possibly offering a quicker and more affordable path to fault-tolerant quantum computing than the more established superconducting technologies.
Groove Quantum has evolved from a research-focused spin-out to a significant competitor in the battle to create the most potent computers in the world with its record-breaking processor and a roadmap aimed at modular 100-qubit cells.
