CliffordGate not correctly matching supported gates

[lucas-slattery]

.upper() method preventing matching CliffordGates because it is comparing against the .keys() method of the case insensitive dict which doesn't return all upper keys.

https://github.com/NVIDIA/cuQuantum/blob/main/python/cuquantum/pauliprop/experimental/operators.py#L170

i.e. "iSWAP".upper() = "ISWAP" which is not in supported gates (but "iSWAP" is)

Thank you for pointing out this bug! We will include a fix in an upcoming release.

Hi Lucas,
In the meantime, you can use the below workaround in your own file (after importing cuquantum.pauliprop.experimental) to avoid having to modify the python source:

# monkey patch Clifford name validation
from cuquantum.pauliprop.experimental._internal import typemaps
CliffordGate.SUPPORTED_GATES |= frozenset(k.upper() for k in CliffordGate.SUPPORTED_GATES)
typemaps.CLIFFORD_MAP |= {k.upper():v for k,v in typemaps.CLIFFORD_MAP.items()}

Apologies for the nuisance!

Great thanks for the update!
