Concise monthly summary for 2025-11: Delivered feature improvements across two repositories (qibocal and qibolab_platforms_qrc) that directly enhance measurement accuracy, calibration reliability, and experiment reproducibility. Ramsey protocol curve fitting parameters were improved to yield more accurate initial guesses, and resonator calibration with updated spectroscopy frequencies were implemented to improve calibration accuracy and quantum measurement precision. These changes increase data quality, reduce variability in calibration measurements, and support faster, more reliable experimental cycles.
