AccountProvider

class AccountProvider(credentials, factory)

기반 클래스: ProviderV1

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 AccountProvider instance. For example:

backend_service = provider.service('backend')
backend_service = provider.service.backend

Since IBMQBackendService is the main service, some of the backend-related methods are available through this class for convenience.

The backends() method returns all the backends available to this account:

backends = provider.backends()

The 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 backend attribute to reference a backend. As an example, to retrieve the same backend from the example above:

simulator_backend = provider.backend.ibmq_qasm_simulator

참고

The backend attribute can be used to autocomplete the names of backends available to this provider. To autocomplete, press tab after 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.
