March 2026: Focused on stabilizing the RF Sequencer workflow in qibocal to prevent errors from misrouted module references. Delivered a critical bug fix that enforces RF module list boundaries during sequencing, reducing runtime exceptions and improving data integrity for RF experiments. The change safeguards sequencing operations when a sequencer points to an invalid or non-RF module, lowering support overhead and enabling smoother automated runs.

February 2026 monthly update: Delivered a major overhaul of the mixer calibration workflow and data model for qibocal, plus targeted bug fixes, resulting in more reliable, scalable calibration across multiple outputs and improved observability for operators and engineers.

January 2026 (2026-01) monthly summary for qibocal (qiboteam/qibocal). Focused on reliability, data integrity, and calibration workflow improvements across spectroscopy, attenuation/punchout data handling, and calibration framework. Delivered measurable business value by optimizing computational paths, strengthening per-qubit data handling, and tightening calibration practices to reduce runtime and setup effort in qubit characterization pipelines.

December 2025: Delivered the Qubit Spectroscopy Batched Frequency Range Processing feature for qibocal, enabling LO frequency updates in batches across wideband ranges to improve throughput and bandwidth utilization. Implemented batch-based LO scheduling with the LO assumed at the batch center to maximize bandwidth while noting potential mixer calibration needs. Added comprehensive documentation detailing batch calculations, behavior when sweep width exceeds the IF bandwidth, and routine operation. Fixed a critical edge-case where the new LO was more than 500 MHz away from the target frequency in parameters.json, ensuring correct LO application within batch processing. Documentation updates accompany these changes and support maintainability.

In November 2025, delivered key feature enhancements for resonator punchout measurement in qibocal, enabling LO attenuation sweeps to determine critical power and improve qubit resonator calibration. This work included refactoring to support LO frequency/attenuation updates, improved parameter handling, clearer attenuation ranges, and documentation updates. The efforts improved measurement accuracy and reliability, streamlined calibration workflows, and set a solid foundation for future experiments and maintainable code.

2025-10 Monthly Summary for qibolab: Delivered a Unified Qubit Elements Dictionary for Quantum Gate Operations, aggregating single-qubit elements and couplers into a single dictionary to simplify gate modeling and usage across configurations. This improves developer productivity and reduces errors in gate operation mappings. Maintained system stability with no major bugs reported; changes pass CI and align with ongoing maintainability efforts. Commit reference included: a2681586b336450ffdad931134438f648faf64fb.

February 2025 monthly summary for qibocal repository focused on key achievements, business value, and technical excellence.
