Required prerequisites
- [X] 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.
- [X] Make sure you've read the documentation. Your issue may be addressed there.

- [ ] If possible, make a PR with a failing test to give us a starting point to work on!
Describe the bug
Runtime error when using np arrays with dtype=cudaq.complex()
on remote simulator.
Steps to reproduce the bug
test.py
import numpy as np
import cudaq
cudaq.set_target("remote-mqpu", url="localhost:3030")
c = np.array([1. / np.sqrt(2.), 1. / np.sqrt(2.), 0., 0.],
dtype=cudaq.complex())
state = cudaq.State.from_data(c)
@cudaq.kernel
def kernel(s: cudaq.State):
q = cudaq.qvector(s)
counts = cudaq.sample(kernel, state)
assert '00' in counts
assert '10' in counts
Run commands (in parallel):
bin/cudaq-qpud --port 3030
python3 test.py
Result:
RuntimeError: [sim-state] invalid data precision.
Note: changing the dtype to complex
works.
Expected behavior
Runs successfully when using cudaq.complex()
dtype on both nvidia
and remote-mqpu
targets.
Is this a regression? If it is, put the last known working version (or commit) here.
