Description

Draft PR enabling CI tests against cuda-quantum release 0.15.0 (plus a few specific commits). See the branch git history for details on which commits from cudaqx were reverted.

In addition to the PR CI, I also successfully built the cudaqx-dev image locally. I have not run the CI action to build the dev image.

Runtime / performance impact

Self-review checklist

Please confirm each item before requesting review. Check [x] or strike
through and explain.

Before requesting review

  • I reviewed my own full diff in GitHub or my editor.
  • PR is in Draft if it is not yet ready for review.
  • Temporary / debugging changes have been removed.
  • Local test logs reviewed; no unexplained warnings or errors.
  • CI logs reviewed; no unexplained warnings or errors.
  • Full CI has been run.

Scope and size

  • PR is under ~1000 lines, or an exception is justified in the description.
  • Refactoring-only changes are isolated in their own PR(s).
  • No existing tests were disabled or modified just to make this PR pass
    (if so, an issue has been raised).

Tests

  • New functionality has new tests.
  • Tests fail if the new functionality is broken (including crashes), not
    just when it is missing.
  • Negative tests added where exceptions are expected.
  • Truth data added where simple EXPECT_* / assert checks are
    insufficient for algorithmic correctness.
  • CI runtime impact considered; team notified if significant.

Documentation

  • Public-facing APIs have Doxygen docs.
  • User-visible behavior changes have public docs, or a follow-up is
    tracked.

Code style

  • Naming follows the existing convention (snake_case vs camelCase) for
    the area being modified.

Dependencies

  • No new third-party dependencies, or the team has been notified and
    OSRB tickets filed.

Apply cuda-quantum CMake patch with reduced context

build_cudaq.sh patches CMakeLists.txt (Python find_package Development ->
Development.Module), but upstream cuda-quantum #4698 restructured the
python/nanobind block, shifting the surrounding context so `git apply` can no
longer locate the hunk (hit when .cudaq_version points at a ref that includes
Non-interactive on purpose: `patch` can hang on a File-to-patch prompt in CI.
