There was a problem hiding this comment.
Thanks @vincentmr
No major concerns from me. Feel free to ignore comments if they are irrelevant.

Before submitting
Please complete the following checklist when submitting a PR:
All new features must include a unit test.
If you've fixed a bug or added code that should be tested, add a test to the
testsdirectory!All new functions and code must be clearly commented and documented.
If you do make documentation changes, make sure that the docs build and
render correctly by running
make docs.Ensure that the test suite passes, by running
make test.Add a new entry to the
.github/CHANGELOG.mdfile, summarizing thechange, and including a link back to the PR.
Ensure that code is properly formatted by running
make format.When all the above are checked, delete everything above the dashed
line and fill in the pull request template.
Context:
The
LM::multiQubitOpkernel usesbitswapto generate the SV indices on the fly. This does not work when the target wires are such that the corresponding bit positions overlap after swap (i.e. when there are a bunch of them with high target indices).Description of the Change:
Add failing multi-qubit gate tests. Introduce a generic
revWireParityfunction and fixLM::multiQubitOp.The corresponding L-Kokkos functors are also broken (gates and expvals). Add failing multi-qubit expval tests and fix gate and expval functors.
