There are several places where we modify JAX during compilation.
Just to list some:
```python
# Required for JAX tracer objects as PennyLane wires.
# pylint: disable=unnecessary-lambda

### Expected behavior
When post-processing the output of a quantum circuit that returns a torch layer, the gradient of the `torch.sqrt()` function at the point '0' should be defined as 0. According…

When I run the code for linear ODE
inits = torch.tensor(cvqnn_layers_all(L, M, seed=0), dtype=torch.float64)
Shows an error: len() of unsized object
How can I fix it?

For some reason wheels are not uploaded to PyPi due to an error, see the error (and log) here: https://github.com/PennyLaneAI/pennylane-lightning/runs/2477011891?check_suite_focus=true#step:4:46

### Expected behavior
`qml.mutual_info` and `qml.vn_entropy` work with any type of shot vectors.
### Actual behavior
Multiple copies of the same shot number raise an error. The issue is that the `Q…

After parametrized gates (with symbolic parameters) of Cirq circuits will be supported (#939 and #911), it would be good to
support parametrized gates of other circuit types too. This issue is to kee…

### Context
Catalyst has recently added support for executing quantum programs in NVIDIA's CUDA Quantum platform. For example, in the following code, we see two identical quantum programs. Both pr…
