Month: 2025-07 — Delivered substantial readout optimization improvements in qibocal with expanded test coverage, documentation, and code quality enhancements. Key work focused on refactoring and upgrading the resonator readout pipeline, adding QND readout metrics, and ensuring test and workflow alignment with the main branch. The changes improve measurement fidelity, reliability, and maintainability, accelerating future feature delivery and reducing maintenance costs.

Month: 2025-05. Focused on improving documentation clarity and formatting consistency for R_x rotations in the qibocal repository. Delivered targeted documentation cleanup that corrected a typo in the chevron.rst mathematical formula and standardized formatting for R_x("pi/2") rotations in flipping.rst and rabi.rst, improving accuracy and readability. This work reduces onboarding time for new contributors and lowers the risk of misinterpretation when configuring rotations in experiments. Key commit reference: 39eae062d3393e55cd5c346e51485c043d492100 (fix: fix issues in doc display).

April 2025: Substantial improvements to the resonator optimization workflow in qibocal, including protocol enhancements, robust QND metric evaluation, and new QND_pi visualization. Fixed critical plotting and QND computation issues, stabilized data acquisition and readout characterization, and expanded analytics to support pi-pulse QND measurements. Result is faster, more reliable resonator tuning with actionable metrics driving design decisions.

March 2025 monthly summary for qibocal team. Focused on delivering robust features, expanding test coverage, and hardening CI/tools to accelerate development velocity and reduce risk. The work spanned cryoscope, acquisition, resonator optimization, readout workflows, and extensive plotting/reporting, with targeted fixes to maintain stability across modules.

February 2025 monthly summary for qibocal (qiboteam/qibocal). Focused on delivering comprehensive documentation, protocol enhancements, and robust numerical modeling improvements that directly support onboarding, maintainability, and accuracy of results. The month saw a suite of feature deliveries across documentation, code, and protocol layers, together with targeted bug fixes to stabilize the modeling pipeline and improve result fidelity.
