Informations

• Qiskit Aer version: 0.16.1
• Python version: 3.12
• Operating system: linux arm

What is the current behavior?

Only for version 0.16.1, our CI fails only for linux ARM and for Python 3.12 (3.11 and 3.10 work fine as well as v0.16.0), see e.g. https://github.com/cda-tum/mqt-bench/actions/runs/13525645197/job/37795417319 for details. The error message is:

ImportError while importing test module '/home/runner/work/mqt-bench/mqt-bench/tests/test_cli.py'.
Hint: make sure your test modules/packages have valid Python names.

Steps to reproduce the problem

Unfortunately, I do not have the time to reduce this to a smaller example.

What is the expected behavior?
