Release Notes¶

0.9.1¶

Upgrade Notes¶

qiskit_ibm_runtime.QiskitRuntimeService.jobs() now has a backend_name parameter that can be used to only return jobs run with the specified backend.

Allow the user to store account details in a file specified by the user in the parameter. filename. The default remains ~/.qiskit/qiskit-ibm.json. Example of usage: Ex:

QiskitRuntimeService.save_account(channel="ibm_quantum",
                                  filename="~/my_account_file.json",
                                  name = "my_account",
                                  token="my_token")
service = QiskitRuntimeService(channel="ibm_quantum", 
                               filename="~/my_account_file.json", 
                               name = "my_account",)

Deprecation Notes¶

backend is no longer a supported option when using qiskit_ibm_runtime.Session.run(). Sessions do not support multiple cross backends. Additionally, an exception will be raised if a backend passed in through options does not match the original session backend in an active session.

Bug Fixes¶

ECRGate and CZGate mappings have been added to the Target constructor to fix a tranpile bug.

Other Notes¶

Since error messages from a failing job may be long, we shortened them so that they begin from the last Traceback in the message.
