Summary

close Renew example codes in README #1806
In REAME, use IBMProvider instead qiskit.providers.ibmq to creare provider
Use NoiseModel.from_backend_properties to create noise model since IBMQ,get)backend is not longer available
Add noise_model to AerSimulator
Tested in IBM-Q

The same as above,

PR 1831 fixed the REAME #1806 problem, 5 hours earlier than PR 1832. This is my first time to submit a PR. Forgot to link the file.

Fix #1806

Tests / tests_windows (3.9, windows-2019) (pull_request): Install Aer Windows Failed has nothing to do with my PR #1831 which only updates README file for issue #1831

This is a fix for documentation. You do not need to check results of CI tests. Our CI is unstable (sometimes Windows's compiler fail due to memory shortage).

README.md

+group = "open"
+project = "main"
+backend_name = "ibmq_lima"
+backend = provider.get_backend(backend_name, instance=f"{hub}/{group}/{project}")


I think README example should be simple. Could you change the codes to get aersim_backend as follows?

backend = FakeVigo() aersim_backend = AerSimulator.from_backend(backend)

Thanks. I made the change as you suggested and also added from qiskit.providers.fake_provider import FakeVigo. The code runs well in IBM-q well.

README.md


 # Perform noisy simulation
-result_noise = qiskit.execute(circ, aersim_backend).result()
+result_noise = aersim_backend.run(circ, shots=1000).result()


shots is optional. So, please just call run(circ) here.

Thanks. shots=1000 has been removed for both ideal and noisy backend.

davidlearn · 2023-06-01T12:29:28Z

Thank you. All done.
