June 2025 monthly summary for qiboteam/qibocal focused on strengthening visualization fidelity and calibration accuracy to drive faster, more reliable decision-making in optimization analysis and TWPA calibration.

Monthly summary for 2025-05: Focused on calibration precision, hardware safety, and data fidelity. Key features delivered include SNZ gate tuning routines implemented with new Python modules snz_optimize_t_idle and snz_optimize_t_idle_vs_t_tot, with protocol init exposure to enable improved two-qubit calibration (commit 69ca6086). Cryoscope gained configurable sampling_rate and updated dependent calculations to support operation with sampling rates different from 1Gsps, while simplifying the API by removing explicit sampling_rate from parameters (commits 57344cbe and ecefa842). Minor documentation improvement fixed the beta_param docstring (commit 55dab8d6). A TWPA channel reference fix corrected the channel from lo to twpa_pump to ensure accurate frequency and power calculations (commit 7d59908d).

April 2025 monthly summary for qiboteam/qibocal focusing on reliability, data fidelity, and calibration efficiency for multi-qubit operations. Key work included fixes to pulse sequence generation for multi-CZ operations, corrections to SNZ sweep logic and parameter ranges, and the introduction of a dedicated t_idle optimization routine. The work strengthened gate calibration reliability, improved data quality, and accelerated optimization cycles, with clear demonstrations of automation, data fitting, and visualization.

March 2025 focused on enabling hardware revision compatibility for the platform and strengthening the two-qubit gate calibration workflow. Delivered platform hardware compatibility and a release upgrade for qibolab_platforms_qrc, enabling support for the latest octave hardware revision, revised port mappings, and cluster/controller identification. Version bumped to 0.2 with adjusted platform parameters to match new specs. Implemented a robust calibration framework for qubit pair 12, delivering preliminary and final calibrations for two-qubit gates (12 and 24), with recalibration cycles and refactored routines to improve accuracy and reliability. These changes reduce integration risk for new hardware and improve gate fidelity.

February 2025 monthly summary for qibocal (qiboteam/qibocal repository). Focused on correcting data processing correctness in Resonator Frequency Protocol by fixing indexing for voltage_i and voltage_q, which improved qubit model fitting accuracy and data reliability. The change enhances measurement quality and reduces rework due to incorrect data extraction. Collaborations and code hygiene maintained to ensure traceability of fixes.
