TECHNOLOGY
Why Germanium?
Germanium hole-spin qubits deliver the perfect combination of scalability, speed, and compatibility with existing semiconductor manufacturing processes. Unlike competing qubit platforms, germanium integrates directly into standard CMOS fab lines.
- Room-temperature-compatible electrical control
- Low-power spin manipulation via electric fields
- Naturally small footprint — thousands of qubits per chip
- Exceptional coherence times in optimized devices
From Transistor to Qubit
Groove Quantum leverages decades of semiconductor knowledge to define qubits using gate-defined quantum dots in germanium quantum wells. The same lithographic techniques used to make transistors are used to define qubits — making scale-up a matter of engineering, not physics.
- Gate-defined quantum dot architecture
- Spin-orbit coupling for fast, all-electric qubit control
- Multiplexed readout compatible with cryo-CMOS electronics
Semiconductor Manufacturing
Our devices are fabricated using industry-standard photolithography and epitaxial growth, enabling production at established semiconductor foundries. This foundry-compatible approach dramatically reduces time-to-market and cost compared to bespoke qubit fabrication methods.
- Compatible with 300mm wafer processes
- Scalable to thousands of qubits per chip
- Leverages existing fab infrastructure
