Rigetti Computing is seeking an experienced Quantum Engineer to drive two-qubit gate performance on tunable-coupler superconducting quantum processors. Two-qubit gate fidelity is a critical challenge in quantum computing and central to the roadmap toward error correction.
In this role, you will design, execute, and interpret experiments that advance near- and long-term gate performance at scale. You will identify dominant sources of two-qubit gate error on the processors, isolate their physical origins, and eliminate them through pulse engineering, calibration methodology, error suppression strategies, or feedback to device design and fabrication teams. Your conclusions will directly inform device design, control strategy, and platform-level decisions.
This is a role with substantial autonomy and ownership. You will directly influence the technical direction for gate performance work through rigorous design and execution of test plans, measurement and improvement of relevant metrics, error budgeting, and shaping of research priorities. You will work in a deeply collaborative environment spanning device design, fabrication, control systems, software, theory, and R&D, turning proofs of concept into robust procedures that scale across hundreds of qubit pairs.
You will be expected to drive technical excellence in quantum gate calibration, develop novel measurement and improvement methodologies, and contribute to the broader quantum computing platform strategy.
