Quantum Machines Achieves 99.5% Two-Qubit Gate Fidelity Operating Rigetti’s Novera QPU
AI-summarised brief · reviewed before publication
Quantum Machines has operated Rigetti Computing's Novera superconducting quantum processing unit using external control hardware and software, reaching a 99.5% median two-qubit gate fidelity. The onsite optimization process achieved full calibration within ten days, matching the peak internal calibration metrics recorded by the hardware manufacturer. This validates that high-performance superconducting processors can maintain stable execution parameters when decoupled from the developer's proprietary control infrastructure. The results were achieved using the OPX1000 orchestration platform and QUAlibrate automation software. The Novera processor is a 9-qubit superconducting QPU with a square lattice of tunable transmons.
💡 Why It Matters
- · Decoupling the processor substrate from the underlying control infrastructure addresses an infrastructure bottleneck for laboratories managing multi-vendor installations, simplifying operational requirements for error mitigation as systems scale.
- · This enables research groups to advance custom algorithm prototyping and error correction experiments with direct physical access to system parameters.
