- class AccountProvider(credentials, factory)¶
Provider for a single IBM Quantum Experience account.
The account provider class provides access to the IBM Quantum Experience services available to this account.
You can access a provider by enabling an account with the
IBMQ.enable_account()method, which returns the default provider you have access to:
from qiskit import IBMQ provider = IBMQ.enable_account(<INSERT_IBM_QUANTUM_EXPERIENCE_TOKEN>)
To select a different provider, use the
IBMQ.get_provider()method and specify the hub, group, or project name of the desired provider.
Each provider may offer different services. The main service,
IBMQBackendService, is available to all providers and gives access to IBM Quantum Experience devices and simulators.
You can obtain an instance of a service using the
service()method or as an attribute of this
AccountProviderinstance. For example:
backend_service = provider.service('backend') backend_service = provider.service.backend
IBMQBackendServiceis the main service, some of the backend-related methods are available through this class for convenience.
backends()method returns all the backends available to this account:
backends = provider.backends()
get_backend()method returns a backend that matches the filters passed as argument. An example of retrieving a backend that matches a specified name:
simulator_backend = provider.get_backend('ibmq_qasm_simulator')
It is also possible to use the
backendattribute to reference a backend. As an example, to retrieve the same backend from the example above:
simulator_backend = provider.backend.ibmq_qasm_simulator
backendattribute can be used to autocomplete the names of backends available to this provider. To autocomplete, press
provider.backend.. This feature may not be available if an error occurs during backend discovery. Also note that this feature is only available in interactive sessions, such as in Jupyter Notebook and the Python interpreter.

Return a single backend matching the specified filtering.
Check if this provider has access to the service.
