Required prerequisites

• Consult the security policy. If reporting a security vulnerability, do not report the bug using this form. Use the process described in the policy to report the issue.
• Make sure you've read the documentation. Your issue may be addressed there.
• Search the issue tracker to verify that this hasn't already been reported. +1 or comment there if it has.
• If possible, make a PR with a failing test to give us a starting point to work on!

Describe the bug

The $U3$ gate as described by the Python side of the documentation (https://nvidia.github.io/cuda-quantum/latest/api/default_ops.html#u3) fails to work, returning some sort of compilation error.

Steps to reproduce the bug

import cudaq
import numpy as np

@cudaq.kernel
def tryu3():
    qubit = cudaq.qubit()
    u3(np.pi/4., np.pi/3, np.pi/5, qubit)

result = cudaq.sample(tryu3, shots_count=2**12)

returns

CompilerError: 3854654959.py:4: error: unhandled function call - u3, known kernels are dict_keys([])
	 (offending source -> u3(np.pi / 4.0, np.pi / 3, np.pi / 5, qubit))

Expected behavior

It should work since it is documented. I do see a note about it being available for simulation only, not sure if it's related. Also, the u3 call needs to be fixed to u3(np.pi, np.pi, np.pi / 2, qubit) since the qubit was defined by the variable qubit in the line above, not q.

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression

Environment

• CUDA Quantum version: 0.7.0
• Python version: 3.9.18
• C++ compiler: gcc/11.4.0
• Operating system: Red Hat Enterprise Linux 8.8

Suggestions

No response

[babreu-ncsa]

It also does not work outside a kernel:

qubit = cudaq.qubit()
u3(np.pi, np.pi, np.pi / 2, qubit)

gives

NameError: name 'u3' is not defined

Nevermind! I found the issue.... u3 is not on v0.7.0!
