qiskit.providers.ibmq.experiment.ExperimentService¶

class ExperimentService(provider, access_token)[ソース]¶

Provides experiment related services.

This class is the main interface to invoke IBM Quantum Experience experiment services, which allow you to create, delete, update, query, and retrieve experiments, experiment plots, and analysis results. The experiment attribute of AccountProvider is an instance of this class, and the main syntax for using the services is provider.experiment.<action>. For example:

from qiskit import IBMQ
provider = IBMQ.load_account()

# Retrieve all experiments.
experiments = provider.experiment.experiments()

# Retrieve experiments with filtering.
experiment_filtered = provider.experiment.experiments(backend_name='foo')

# Retrieve a specific experiment using its ID.
experiment = provider.experiment.retrieve_experiment(EXPERIMENT_ID)

# Upload a new experiment.
from qiskit.providers.ibmq.experiment import Experiment
new_exp = Experiment(
    provider=provider,
    backend_name=backend_name,
    experiment_type='test',
    tags=['qiskit-test']
)
provider.experiment.upload_experiment(new_exp)

# Update an experiment.
new_exp.end_datetime = datetime.now()
provider.experiment.update_experiment(new_exp)

# Delete an experiment.
provider.experiment.delete_experiment(EXPERIMENT_ID)

Similar syntax applies to analysis results and experiment plots. Classes Experiment and AnalysisResult encapsulate data of an experiment and an analysis result, respectively.

Retrieve all experiments, with optional filtering.

By default, results returned are as inclusive as possible. For example, if you don’t specify any filters, all experiments visible to you are returned. This includes your own experiments as well as those shared with you, from all providers you have access to (not just from the provider you used to invoke this experiment service).
