Apr 1, 2026April 2026 monthly summary for qilimanjaro-tech/qililab: Delivered a critical bug fix to remove the stale sequence upload cache, ensuring sequences are re-uploaded after every acquisition and thereby guaranteeing correct bin allocation and preventing execution errors. This change improves reliability of the acquisition pipeline across clusters. The fix is a temporary workaround until firmware v0.13 and the upcoming _update_sequence() integration, after which hashing and re-upload logic will be reintroduced to restore efficiency.

Sep 1, 2025Month: 2025-09 — qilimanjaro-tech/qililab bug-fix sprint focusing on reliability and plotting consistency. Delivered two high-impact fixes that align internal calculations with external behavior and prevent performance-time errors, improving stability for hardware communication and data visualization. What was delivered: - QbloxDraw: Correct integration length for acquire_weighted. Integration length is now determined by weight duration rather than runcard parameter to align plotting behavior with qprogram. - QBlox Compiler: Robust handling of long wait durations (multiples of 65532) to prevent errors. Improved remainder handling when calculating wait times for long durations (65532–65535) to avoid failures. Business value: Reduced user-reported plotting and timing errors, stabilized hardware control loops, and ensured consistency between software calculations and hardware expectations. This supports smoother experiment runs and more trustworthy data pipelines. Technologies/skills demonstrated: Python development, edge-case handling for numerical ranges, commit-driven debugging, and collaboration across Qilib lab components.
