Retrieve a job from a retired system

To retrieve jobs from a retired system, you can use code similar to this, depending on the provider from which the job was sent:

For a job run from IBM Provider

from qiskit_ibm_provider import IBMProvider
 
provider = IBMProvider(instance="hub/group/project")
 
#If you want to retrieve a list of jobs
jobs = provider.backend.jobs(backend_name=<backend_name>)
 
#If you want to retrieve a specific job you have the id for
job = provider.backend.retrieve_job(<job_id>)

For a job run from Qiskit Runtime

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>)
