Qubit ZooLandmark germanium hole-spin result showing that strong spin-orbit coupling can support fast universal control without micromagnets. It pushed Ge/SiGe hole qubits from promising materials physics into serious processor-building territory.
Key Results
- Demonstrates a universal gate set in germanium hole quantum dots with local electrical control
- Reports single-qubit fidelity of 99.3% with gate times around 20 ns
- Executes two-qubit logic within about 75 ns while operating near the charge symmetry point
