I think this is good, just opening for CI. Feel free to merge once the corresponding changes in PL go through! |

**Context:** We are in favor of `wires`, just like what we did with `MultiControlledX`. !Note: this involves a big user-interface change. With PL version <=0.40, for ControlledQubitUnitary, we have arg wires to be the target_wires, and the arg control_wires is a positional arg. To be consistent with all the other interfaces, we would like to alter this into wires to be positional and to represent control_wires+target_wires Before: ```python mat = np.eye(2) control_wires = [0] wires = [1] ControlledQubitUnitary(mat, control_wires, wires=wires, control_values=...) ``` After: ```python mat = np.eye(2) wires = [0, 1] ControlledQubitUnitary(mat, wires, control_values=...) ``` where the new `wires` should be the concatenate of old `control_wires` and `wires` **Description of the Change:** Besides the modified test files across the whole codebase involving `ControlledQubitUnitary`, we made the following necessary adjustments beyond the `__init__` method: - classmethod `_unflatten`, `_primitive_bind_call` and method `_controlled` were adjusted accordingly following the new interface - move the `TypeError` regarding empty arg `wires` to the beginning. - add a register for `ControlledQubitUnitary` in `bind_new_parameters.py` following the pattern of `CRX` - modified the direct calls of `ControlledQubitUnitary` inside src files `metric_tensor.py`, `controlled.py` and `matrix_ops.py`. ### **Eco-System** This is an inevitable breaking change, so we need to immediately inform the affected repos that depend on latest PennyLane but only apply corresponding changes after this PR gets merged. - [ ] labs - [ ] Catalyst: [frontend/test/pytest/device/test_decomposition.py](https://github.com/PennyLaneAI/catalyst/blob/286e51910a39c55130de8c1c6a806818a2bcb14b/frontend/test/pytest/device/test_decomposition.py#L52) PennyLaneAI/catalyst#1483 - [ ] Lightning: PR to fix it PennyLaneAI/pennylane-lightning#1047 - - [test_gates.py](https://github.com/PennyLaneAI/pennylane-lightning/blob/290c986e7d087e17dbf3f09c6d2dfc8bd738cc08/tests/test_gates.py#L451) - - [test_gates_and_expval.py](https://github.com/PennyLaneAI/pennylane-lightning/blob/290c986e7d087e17dbf3f09c6d2dfc8bd738cc08/tests/lightning_tensor/test_gates_and_expval.py#L72) - - [test_measurements_class.py](https://github.com/PennyLaneAI/pennylane-lightning/blob/290c986e7d087e17dbf3f09c6d2dfc8bd738cc08/tests/lightning_qubit/test_measurements_class.py#L814) - [ ] QML Demos: [tutorial_classically_boosted_vqe.py](https://github.com/PennyLaneAI/qml/blob/c444cec6201338056304d9d5a293f969a3aeec5e/demonstrations/tutorial_classically_boosted_vqe.py#L451); PR to fix it PennyLaneAI/qml#1310 ### **Plugins** - [x] Pennylane-AQT: No instances of deprecated code found. - [x] Pennylane-Qiskit: No instances of deprecated code found. - [x] Pennylane-IonQ: No instances of deprecated code found. - [x] Pennylane-Qrack: No instances of deprecated code found. - [x] Pennylane-Cirq: No instances of deprecated code found. - [x] Pennylane-Qulacs: No instances of deprecated code found. **Benefits:** Unified interfaces with other controlled ops. **Possible Drawbacks:** This is a hard change to deprecate this arg.
