Retrieve a job from a retired QPU
Use the following code to retrieve a job from a retired QPU.
Passing in a Cloud Resource Name (CRN) or name in the following code is optional. When it is passed in, only backends and jobs from that instance are available. If an instance is not specified, all backends and jobs across all instances in your account are available. In this case, when a backend is specified, an instance that can access that backend is found and used.
from qiskit_ibm_runtime import QiskitRuntimeService
# Load your IBM Quantum account. Replace "<IBM Cloud CRN>" with your desired instance's CRN or name.
service = QiskitRuntimeService(channel="ibm_quantum_platform", instance="<IBM Cloud CRN or Name>")
# 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>)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.
