Upgrade and generalise basis state preparation #6021

KetpuntoG · 2024-07-22T15:46:21Z

This PR complete part of this story: [sc-68521]

Goal: BasisEmbedding is an alias of BasisState. This way, we don't have duplicate code that does the same thing.
In unifying this, I have had to modify some tests due to:

BasisEmbedding and BasisState throw errors such as "incorrect length" with different messages. Now it will always be the same. (test modified for this reason: test_default_qubit_legacy.py, test_default_qubit_tf.py
test_default_qubit_torch.py, test_state_prep.py, test_all_singles_doubles.py and test_uccsd`)
In BasisEmbedding, errors were thrown in __init__ while in BasisState in state_vector. Now they are unified in __init__. For this reason, there were tests where the operator was not initialized correctly but no error was thrown since state_vector was not being called but now they are detected. To correct this, I have modified the tests: test_qscript.py, test_state_prep.py,
Now BasisState does not decompose BasisStatePreparation since we are going to deprecate it. This causes the number of gates after expanding to be affected. In this case I had to modify some test in test_tape.py.

…legacy device for MPI LGPU (#864) ### Before submitting Please complete the following checklist when submitting a PR: - [x] 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 [`tests`](../tests) directory! - [x] 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`. - [x] Ensure that the test suite passes, by running `make test`. - [x] Add a new entry to the `.github/CHANGELOG.md` file, summarizing the change, and including a link back to the PR. - [x] 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:** - PR PennyLaneAI/pennylane#6021 removed code duplication for `BasisEmbedding` and `BasisState`. As the result `BasisState` no longer decomposes to `BasisStatePreparation`. This PR updates Python unit tests to support this generalization of basis state preparation. - PR PennyLaneAI/pennylane#6046 added a facade wrapper class for "legacy" devices.
