BackendConfiguration
class BackendConfiguration(backend_name, backend_version, n_qubits, basis_gates, gates, local, simulator, conditional, open_pulse, memory, max_shots, coupling_map, max_experiments=None, sample_name=None, n_registers=None, register_map=None, configurable=None, credits_required=None, online_date=None, display_name=None, description=None, tags=None, **kwargs)
Backwards compat shim representing an abstract backend configuration.
Initialize a QasmBackendConfiguration Object
Parameters
- backend_name (str) – The backend name
- backend_version (str) – The backend version in the form X.Y.Z
- n_qubits (int) – the number of qubits for the backend
- basis_gates (list) – The list of strings for the basis gates of the backends
- gates (list) – The list of GateConfig objects for the basis gates of the backend
- local (bool) – True if the backend is local or False if remote
- simulator (bool) – True if the backend is a simulator
- conditional (bool) – True if the backend supports conditional operations
- open_pulse (bool) – True if the backend supports OpenPulse
- memory (bool) – True if the backend supports memory
- max_shots (int) – The maximum number of shots allowed on the backend
- coupling_map (list) – The coupling map for the device
- max_experiments (int) – The maximum number of experiments per job
- sample_name (str) – Sample name for the backend
- n_registers (int) – Number of register slots available for feedback (if conditional is True)
- register_map (list) – An array of dimension n_qubits X n_registers that specifies whether a qubit can store a measurement in a certain register slot.
- configurable (bool) – True if the backend is configurable, if the backend is a simulator
- credits_required (bool) – True if backend requires credits to run a job.
- online_date (datetime) – The date that the device went online
- display_name (str) – Alternate name field for the backend
- description (str) – A description for the backend
- tags (list) – A list of string tags to describe the backend
- **kwargs – optional fields
Attributes
num_qubits
Returns the number of qubits.
In future, n_qubits should be replaced in favor of num_qubits for consistent use throughout Qiskit. Until this is properly refactored, this property serves as intermediate solution.
Methods
from_dict
classmethod BackendConfiguration.from_dict(data)
Create a new GateConfig object from a dictionary.
Parameters
data (dict) – A dictionary representing the GateConfig to create. It will be in the same format as output by to_dict().
Returns
The GateConfig from the input dictionary.
Return type
to_dict
BackendConfiguration.to_dict()
Return a dictionary format representation of the GateConfig.
Returns
The dictionary form of the GateConfig.
Return type
dict
