Description

The following tests for noisy simulation fail / crash sporadically in CI:

  1. python/kernel/test_run_async_kernel.py::test_run_async_with_noise
  2. python/tests/builder/test_NoiseModel.py::test_callback_channel

Ref:

These failures are not reproducible locally.

Research direction

Start with python/kernel/test_run_async_kernel.py::test_run_async_with_noise and python/tests/builder/test_NoiseModel.py::test_callback_channel, then inspect the referenced CI job for failure details. Determine why these asynchronous noisy-simulation tests fail or crash sporadically in CI; done means both tests run reliably in CI.
