[BUG] TestGateFusion cases fails

[Ghjk94522]

Informations

• Qiskit Aer version: 0.17.2
• Python version: 3.11.10
• Operating system: ubuntu 22.04
• Nvidia Driver Version: 535.274.02
• CUDA Version: 12.2
• GPU: NVIDIA RTX A6000

What is the current behavior?

When running the command:

test.terra.backends.aer_simulator.test_fusion.TestGateFusion.test_non_kraus_noise_fusion_3___statevector____GPU_batch__

the test case fails and the error msg is:

Captured traceback:
~~~~~~~~~~~~~~~~~~~
    Traceback (most recent call last):

      File "/workspace/qis-env/lib/python3.11/site-packages/ddt.py", line 221, in wrapper
    return func(self, *args, **kwargs)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^

      File "/workspace/qiskit-aer/test/terra/backends/aer_simulator/test_fusion.py", line 264, in test_non_kraus_noise_fusion
    self.assertTrue(meta.get("applied", False), msg="fusion should have been applied.")

      File "/opt/conda/lib/python3.11/unittest/case.py", line 715, in assertTrue
    raise self.failureException(msg)

    AssertionError: False is not true : fusion should have been applied.

which means the applied attribute should be set in meta but it didn't.Could you help investigate whether this is a backend bug, an expected limitation, or an issue in the test logic?

Let me know if more logs or debugging information are needed.

Steps to reproduce the problem

Install qiskit-aer from src.
Run command after installation.

What is the expected behavior?

Test cases pass.

Suggested solutions
