Harnessing the power of germanium to unlock the potential of quantum computation

Scaling quantum technology

The world is hungry for quantum computers, as they promise to solve our most demanding challenges. This new approach to computing is expected to revolutionize fields like security, medicine, and materials research, contributing to a safer and more sustainable world. Yet, these world-changing solutions require millions of qubits.

Germanium  qubits are the solution

At Groove Quantum, we overcome the scalability challenge by using our unique germanium quantum technology. Germanium qubits have a high quality, small footprint and integrate seamlessly into existing semiconductor manufacturing processes, all accelerating scaling. We aim to unlock the full potential of quantum computing and drive innovation.

Semiconductors have powered modern technology and will drive future quantum advancements.

Germanium qubits consist of just a transitor, feature a scalable  size, are built on industry technology
, and have excellent performance


The first digital computers were made of thousands of vacuum tubes. If we would still make computers like this today, our phones would be the size of a skyscraper. The invention of the transistor and the rise of the semiconductor industry marked a turning point. Today, billions of reproducible, high-quality bits fit on a chip the size of a coin, allowing our phones to fit in our pockets.

Likewise, semiconductor germanium qubits hold the key to solving the scalability challenge in quantum computing. At Groove quantum, we leverage this synergy with developments in the semiconductor industry, to scale our quantum chips faster, with additional robustness and at lower costs.


Our team has achieved significant milestones in the field, showcasing the high quality and scalability of germanium qubits.

We backed our expertise with a solid foundation of intellectual property. As pioneers in adopting germanium for quantum technology, we hold valuable know-how and have filed numerous patent applications in the domains of qubit performance, yield, and scalability.
