SimulatorOptions
class SimulatorOptions(noise_model=Unset, seed_simulator=Unset, coupling_map=Unset, basis_gates=Unset)
Bases: object
Simulator options.
For best practice in simulating a backend make sure to pass the basis gates and coupling map of that backend.
Attributes
Parameters
- noise_model (UnsetType | dict | NoiseModel | None)
- seed_simulator (UnsetType | int)
- coupling_map (UnsetType | List[List[int]] | CouplingMap)
- basis_gates (UnsetType | List[str])
basis_gates
Type: UnsetType | List[str]
Default value: Unset
List of basis gate names to unroll to. For example, ['u1', 'u2', 'u3', 'cx']. Unrolling is not done if not set.
Default: all basis gates supported by the simulator.
coupling_map
Type: UnsetType | List[List[int]] | CouplingMap
Default value: Unset
Directed coupling map to target in mapping. If the coupling map is symmetric, both directions need to be specified. Each entry in the list specifies a directed two-qubit interaction, e.g: [[0, 1], [0, 3], [1, 2], [1, 5], [2, 5], [4, 1], [5, 3]].
Default: None, which implies no connectivity constraints.
noise_model
Type: UnsetType | dict | NoiseModel | None
Default value: Unset
Noise model for the simulator. This option is only supported in local testing mode.
Default: None.
seed_simulator
Type: UnsetType | int
Default value: Unset
Random seed to control sampling.
Default: None.
Methods
set_backend
set_backend(backend)
Set backend for simulation. This method changes noise_model, coupling_map, basis_gates according to given backend.
Parameters
backend (BackendV2) – backend to be set.
Raises
MissingOptionalLibraryError – if qiskit-aer is not found.
Return type
None
