Quantum Machines Achieves 99.5% Median Two-Qubit Gate Fidelity on Rigetti Novera QPU with OPX1000 Platform
Summarize this article with:
Performance Milestone: Quantum Machines reaches 99.5% median two-qubit gate fidelity operating Rigetti’s commercially available Novera 9-qubit superconducting QPU.Record Achievement: Highest full-system Novera performance recorded to date with an external control systems partner.Ecosystem Expansion: QM Orchestration Platform powers Novera deployments at Fermilab, Montana State University, Horizon Quantum, and TreQ’s multi-QPU system.Quantum Machines, a provider of hybrid quantum-classical control solutions, announced on May 27, 2026, that it has successfully operated Rigetti Computing’s commercially available Novera™ 9-qubit superconducting quantum processing unit using its OPX1000 hardware and QUAlibrate software, reaching 99.5% median two-qubit gate fidelity. The result represents the highest full-system Novera performance achieved to date between Rigetti and a control systems partner.Rigetti’s Novera is a commercially available 9-qubit superconducting QPU designed for on-premises deployment in research and development labs, based on the same underlying architecture used in the company’s larger superconducting quantum systems. A Quantum Machines team performed onsite calibration at Rigetti using the OPX1000 control stack together with QUAlibrate calibration automation software.The workflow included automated calibration routines, parallelized tuning across the full device, real-time control optimization, and continuous system-level performance monitoring, delivering consistent low-error quantum operations across the entire chip.The milestone demonstrates that advanced superconducting quantum processors can achieve stable, high-performance operation outside the original hardware developer’s internal environment, supporting broader adoption in national laboratories and commercial deployments. It reflects the industry shift toward scalable control infrastructure, calibration automation, real-time feedback, and integrated quantum-classical systems capable of maintaining performance at scale.The Quantum Machines Quantum Orchestration Platform is already deployed with Novera systems at Fermilab, Montana State University, Horizon Quantum, and selected by TreQ for its multi-QPU system to develop the first Open Architecture Quantum (OAQ) specification.Find out more here.
