Retrieve a job from a retired QPU
Use the following code to retrieve a job from a retired QPU.
from qiskit_ibm_runtime import QiskitRuntimeService
# Load your IBM Quantum account(s). Replace "hub/group/project" with your desired instance
service = QiskitRuntimeService(channel="ibm_quantum", instance="hub/group/project")
# Retrieve a single job by id
job = service.job(<job_id>)
# Retrieve a batch of jobs. Filtering options can be found in the QiskitRuntimeService.jobs api reference
jobs = service.jobs(backend_name=<backend_name>)Deprecated provider packages
service.jobs() returns jobs run from both qiskit-ibm-runtime and the deprecated qiskit-ibm-provider package. Jobs submitted by the older (also deprecated) qiskit-ibmq-provider package are no longer available.
