Groove Quantum

Groove Quantum develops scalable quantum computers based on germanium spin qubit technology, leveraging the synergy between semiconductor manufacturing processes and quantum chip fabrication to overcome the scalability challenge in quantum computing. Germanium qubits consist of just a single transistor, feature a small footprint, integrate seamlessly into existing CMOS semiconductor manufacturing processes, and deliver excellent performance with high fidelity. The company has achieved significant milestones including demonstrating the world's first 2D grid of semiconductor qubits (Nature, 2021), operating the first germanium quantum processor (Nature, 2020), achieving world-leading single-qubit gate fidelity exceeding 99.99% (Nature Communications, 2023), inventing scalable architectures with sub-linear I/O scaling (Nature Nanotechnology, 2023), and demonstrating a novel low-power qubit control mechanism in a 10-dot array with two-qubit gate fidelity exceeding 99% (Science, 2024). Groove Quantum holds valuable intellectual property with numerous patent applications in qubit performance, yield, and scalability. Founded in 2024 and headquartered in Delft, Netherlands, the company has raised approximately $20.5 million at the Seed stage from investors including the European Innovation Council, Innovation Industries, 55 North, and Verve Ventures.
