EstimatorOptions
class EstimatorOptions(*args, **kwargs)
Options for V2 Estimator.
Attributes
default_precision
Type: UnsetType | float
Default value: Unset
The default precision to use for any PUB or run() call that does not specify one. Each Estimator PUB can specify its own precision. If the run() method is given a precision, then that value is used for all PUBs in the run() call that do not specify their own.
Default: 0.015625 (1 / sqrt(4096)).
default_shots
Type: UnsetType | int | None
Default value: Unset
The total number of shots to use per circuit per configuration.
If set, this value overrides default_precision.
A configuration is a combination of a specific parameter value binding set and a physical measurement basis. A physical measurement basis groups together some collection of qubit-wise commuting observables for some specific circuit/parameter value set to create a single measurement with basis rotations that is inserted into hardware executions.
If twirling is enabled, the value of this option will be divided over circuit randomizations, with a smaller number of shots per randomization. See the twirling options.
Default: None.
dynamical_decoupling
Type: DynamicalDecouplingOptions | Dict
Default value: FieldInfo(annotation=Union[DynamicalDecouplingOptions, Dict], required=False, default_factory=DynamicalDecouplingOptions)
Suboptions for dynamical decoupling. See DynamicalDecouplingOptions for all available options.
environment
Type: EnvironmentOptions | Dict
Default value: FieldInfo(annotation=Union[EnvironmentOptions, Dict], required=False, default_factory=EnvironmentOptions)
execution
Type: ExecutionOptionsV2 | Dict
Default value: FieldInfo(annotation=Union[ExecutionOptionsV2, Dict], required=False, default_factory=ExecutionOptionsV2)
Execution time options. See ExecutionOptionsV2 for all available options.
experimental
Type: UnsetType | dict
Default value: Unset
Experimental options. These options are subject to change without notification, and stability is not guaranteed.
max_execution_time
Type: UnsetType | int
Default value: Unset
resilience
Type: ResilienceOptionsV2 | Dict
Default value: FieldInfo(annotation=Union[ResilienceOptionsV2, Dict], required=False, default_factory=ResilienceOptionsV2)
Advanced resilience options to fine-tune the resilience strategy. See ResilienceOptionsV2 for all available options.
resilience_level
Type: UnsetType | int
Default value: Unset
How much resilience to build against errors. Higher levels generate more accurate results, at the expense of longer processing times.
-
0: No mitigation.
-
1: Minimal mitigation costs. Mitigate error associated with readout errors.
-
2: Medium mitigation costs. Typically reduces bias in estimators but
is not guaranteed to be zero bias.
Refer to the Configure error mitigation for Qiskit Runtime guide for more information about the error mitigation methods used at each level.
Default: 1.
seed_estimator
Type: UnsetType | int
Default value: Unset
Seed used to control sampling.
Default: None.
simulator
Type: SimulatorOptions | Dict
Default value: FieldInfo(annotation=Union[SimulatorOptions, Dict], required=False, default_factory=SimulatorOptions)
twirling
Type: TwirlingOptions | Dict
Default value: FieldInfo(annotation=Union[TwirlingOptions, Dict], required=False, default_factory=TwirlingOptions)
Pauli twirling options. See TwirlingOptions for all available options.
