Javier Villegas developed and optimized calibration and control features for quantum hardware in the qiboteam/qibolab_platforms_qrc and qiboteam/qibocal repositories. He enhanced quantum readout fidelity and calibration stability for the D2 system by refining data handling and introducing extra drive channels, improving operational accuracy in quantum experiments. His work included refactoring calibration modules for mixers and instruments, enabling flexible instrument support and more reliable data processing. Javier also implemented multi-queue management to increase throughput in queue-driven workflows. Using Python and JSON, he focused on backend development, configuration management, and data analysis, delivering robust, maintainable solutions without major bug regressions.
February 2026 accomplishments focused on calibration workflow enhancements and throughput improvements across qibocal and qibolab_platforms_qrc. Key features delivered include: 1) Mixer Calibration: Flexible Instrument Handling and Plotting Improvements — enables flexible handling of instrument types in mixer calibration and fixes plotting to correctly handle fit parameters, improving calibration usability and accuracy. 2) Calibration Module Refactor and Cleanup — extensive refactors to calibration logic for mixers and instruments to improve data handling, clarity, and maintainability across the calibration workflow. 3) Multi-Queue Management Enhancement — updates to queues.json to support multiple queue entries, enabling the system to manage several queues concurrently and boost throughput. These changes are complemented by co-authored contributions across multiple commits, strengthening code quality and collaboration. Overall impact includes reduced calibration setup time, improved reliability of calibrations across instrument types, and higher throughputs in queue-driven workflows. Technologies demonstrated include Python, data handling, plotting adjustments, protocol refactoring, and collaborative development practices (co-authored commits).
