Description

In order to implement CUDA, I had to override some functionality in Catalyst.

        with Patcher(
            (catalyst.pennylane_extensions.QFunc, "extract_backend_info", cudaq_backend_info),
            (qml.QNode, "__call__", QFunc.__call__),
        ):

I think third party compilers might have to do something similar if they follow a similar approach to CUDA-quantum's implementation.

Research direction

Start by reading the Patcher usage around catalyst.pennylane_extensions.QFunc.extract_backend_info, qml.QNode.call, and QFunc.call. Determine the API changes needed for third-party compilers following the CUDA-Q approach; done means such compilers no longer need to override these functions manually.
