QMEstimatorV2¶

class QMEstimatorV2(backend: QMBackend, options: QMEstimatorOptions | dict | None = None)[source][source]¶

Bases: BaseEstimatorV2

QOP-aware Qiskit V2 Estimator for QMBackend.

Computes expectation values and standard errors from QUA execution with optional abelian grouping and real-time parameter streaming.

Create an estimator bound to a QM backend.

Parameters:

backend – Target backend with QuAM-derived Target.
options – QMEstimatorOptions instance or options dict.

Run the estimator on the given pubs.

Parameters:

pubs – Estimator pubs (circuit, observables, parameter values, precision).
precision – Target precision. Defaults to default_precision.

Returns:

QMEstimatorJob (or IQCC variant) after submission.

property backend: QMBackend¶: Return the QM backend associated with this estimator.
