Bases: ABC(opens in a new tab)
Estimator V2 base class.
An estimator estimates expectation values for provided quantum circuit and observable combinations.
An Estimator implementation must treat the run() method precision=None kwarg as using a default precision value. The default value and methods to set it can be determined by the Estimator implementor.
Methods
run
abstract run(pubs, *, precision=None)
Estimate expectation values for each provided pub (Primitive Unified Bloc).
Parameters
- pubs (Iterable[EstimatorPubLike]) – An iterable of pub-like objects, such as tuples
(circuit, observables)or(circuit, observables, parameter_values). - precision (float(opens in a new tab) | None) – The target precision for expectation value estimates of each run Estimator Pub that does not specify its own precision. If None the estimator’s default precision value will be used.
Returns
A job object that contains results.
