qiskit.providers.ibmq.experiment.ExperimentService¶

class ExperimentService(provider, access_token)[source]¶

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 analysis results, with optional filtering.

Parameters

limit (Optional[int]) – Number of analysis results to retrieve.
backend_name (Optional[str]) – Backend name used for filtering.
device_components (Optional[List[str]]) – Filter by device components. An analysis result’s device components must match this list exactly for it to be included.

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).

Parameters

limit (Optional[int]) – Number of experiments to retrieve. None indicates no limit.
backend_name (Optional[str]) – Backend name used for filtering.
type (Optional[str]) – Experiment type used for filtering.
start_datetime (Optional[datetime]) – Filter by the given start timestamp, in local time. This is used to find experiments whose start date/time is after (greater than or equal to) this local timestamp.
end_datetime (Optional[datetime]) – Filter by the given end timestamp, in local time. This is used to find experiments whose start date/time is before (less than or equal to) this local timestamp.
device_components (Optional[List[str]]) – Filter by device components. An experiment must have analysis results with device components matching the given list exactly to be included.
tags (Optional[List[str]]) – Filter by tags assigned to experiments.
tags_operator (Optional[str]) –
Logical operator to use when filtering by job tags. Valid values are “AND” and “OR”:
- If “AND” is specified, then an experiment must have all of the tags specified in tags to be included.
- If “OR” is specified, then an experiment only needs to have any of the tags specified in tags to be included.
hub (Optional[str]) – Filter by hub.
group (Optional[str]) – Filter by hub and group. hub must also be specified if group is.
project (Optional[str]) – Filter by hub, group, and project. hub and group must also be specified if project is.
exclude_public (Optional[bool]) – If True, experiments with share_level=public (that is, experiments visible to all users) will not be returned. Cannot be True if public_only is True.
public_only (Optional[bool]) – If True, only experiments with share_level=public (that is, experiments visible to all users) will be returned. Cannot be True if exclude_public is True.
exclude_mine (Optional[bool]) – If True, experiments where I am the owner will not be returned. Cannot be True if mine_only is True.
mine_only (Optional[bool]) – If True, only experiments where I am the owner will be returned. Cannot be True if exclude_mine is True.
