BaseEstimator¶

class BaseEstimator(*, options=None)[source]¶

Bases: BasePrimitive, Generic[T]

Estimator base class.

Base class for Estimator that estimates expectation values of quantum circuits and observables.

Creating an instance of an Estimator, or using one in a with context opens a session that holds resources until the instance is close() ed or the context is exited.

Parameters: options -- Default options.

Methods

`run`	Run the job of the estimation of expectation value(s).
`set_options`	Set options values for the estimator.

Attributes

circuits¶

Quantum circuits that represents quantum states.

Returns: The quantum circuits.

observables¶

Observables to be estimated.

Returns: The observables.

options¶

Return options values for the estimator.

Returns: options

parameters¶

Parameters of the quantum circuits.

Returns: Parameters, where parameters[i][j] is the j-th parameter of the i-th circuit.
