Quantum Measurement Engineer – QPU Diagnostics & Calibration

Job description

About Us QuantWare is building the world’s most powerful quantum processors to solve humanity's greatest challenges. We do this with our unique VIO™ technology, the only QPU architecture that breaks the hardware barriers that have held quantum computing back, unlocking the path to MegaQubit quantum processors. With VIO, we are paving the way for the hyper-scale quantum computers that will change the world. And delivering on that vision demands people who don’t shy away from tackling the hardest challenges of our time. That’s where you come in! We are looking for a Senior Quantum Measurement and Calibration Engineer to drive the experimental characterization, diagnostic protocol development, and performance optimization of our next-generation quantum processors. You will be responsible for building advanced diagnostic routines that isolate loss mechanisms, quantify crosstalk, budget gate errors, and improve operational fidelities across our QPUs and development prototypes. You will work in our Quantum Processor team at the core of our measurement efforts, collaborating closely with QPU Design, Measurement and Software Engineers. Your measurements will directly contribute to improving our quantum processor performance and push the edge of what is currently possible. What you’ll be doing Advanced measurement protocols: Create and refine advanced protocols to improve quantum gate and readout fidelities and develop diagnostics tooling to identify performance bottlenecks (e.g. noise and TLS spectroscopy, gate error budgeting). Design and execution of experiments: Design and execute experiments to validate, compare, and benchmark new design elements and layout optimisations (e.g. coupling schemes, filtering, crosstalk mitigations). Data-Driven Feedback: Analyze measurement datasets, report findings with clarity, and lead discussions with the broader engineering teams to translate experimental learnings into device design upgrades. Ownership: Take complete ownership of measurement campaigns – from the initial hypothesis and experiment design through cooldown, data acquisition, analysis, and final reporting. Your Profile 5+ years of hands-on experience in cryogenic measurement of multi-qubit superconducting quantum processors . Extensive experience in diagnosing performance-limiting mechanisms in superconducting quantum processors. Deep understanding of cQED and sup…
