Get Calibration Data
Each job executed on VLQ contains information about calibration data used.
- The calibration information is identified by an
calibration_set_id / observation_set_idUUID. - Current calibration set id is
default.
The id for a particular job may be retrieved from the job.result object as:
# Submit job
job = backend.run(...)
...
# Retrieve calibration set id
job.result()._get_experiment().calibration_set_idVLQ calibration set is available at https://extranet.it4i.cz/vlq-calibration/.
Enter the id into the textbox and click one of the GET buttons.
Set Calibration Data
- Jobs are by default executed using the
defaultcalibration set. - Optionally, alternative calibration may be used. This is set by specifying the UUID when creating the backend object.
# 3. Initialize QaaS
provider = QProvider(PROJECT, token)
