GRAPE Logging Cleanup
This week, I made progress on the QTRL-to-QOC migration.
1. PR for Logging Cleanup
I raised a draft PR for the merge_qtrl branch, which includes the logging cleanup work I did last week:
- Removed QTRL-specific logging from _grape.py and _crab.py.
- Eliminated all qutip_qtrl.logging_utils imports, logger = logging.get_logger(), and logger.debug(...) calls.
Additionally, I created a temporary test_grape.py in the q2/ folder as a quick smoke test to verify grape_unitary() runs without errors and returns a final unitary U_f of type Qobj.
This was only for debugging import issues in q2/grape.py and will be removed in the next commit if not needed.
I also cherry-picked the key comments from PR #47 into this new PR to ensure that prior review feedback was retained.
2. Fidelity Measures Investigation (#46)
I explored the relationship between fidelity measures in QTRL vs. QuTiP.
- Produced a plot by varying the collapse operator (c_op) rate and visualized the differences between the two fidelity definitions.
- Shared the plot and initial findings on Discord for feedback.
3. Issue #47 Updates
- Added a comment on #47 explaining the fix for the TRACEDIFF infidelity mismatch and the approach taken.
- Posted updates on the main Discord channel to keep everyone informed.
