Jan 1, 2026January 2026—Ulm-IQO/qudi-iqo-modules: Delivered focused enhancements to pulse sequencing timing and gating. Implemented a dedicated PulseSequence length calculation method and fixed counting length in t1_sequencing for both gated and ungated counter paths, improving accuracy of measurement information across pulse sequences. Reverted the default gating behavior for fast_counter_dummy from True to False to align with intended operation and prevent inadvertent gating. These changes improve data integrity, repeatability, and reliability of timing-sensitive experiments, while strengthening the module’s sequencing and gating capabilities. Technologies demonstrated: Python, Git-based version control, and domain-specific pulse timing logic.

Oct 1, 2025October 2025 for Ulm-IQO/qudi-iqo-modules focused on improving generator discovery reliability, maintaining documentation quality, and stabilizing typing in scanning probe logic. Delivered an MRO-based PredefinedGenerator discovery that detects generator classes across multi-inheritance hierarchies, with a changelog entry noting the improved pulsed tool chain compatibility. Included a documentation-only fix for code suggestions involving Connector objects (documentation updated in changelog). Reverted explicit type hints in the scanning probe logic to restore the previous typing state, preserving compatibility and stability across the module. Business value: increased accuracy and speed of developer tooling, clearer release notes, and reduced risk of typing regressions in critical scanning workflows.
