mqt.ddsim.primitives.estimator¶

Estimator implementation using DDSIM CircuitSimulator.

Module Contents¶

class Estimator(*, default_precision: float = 0.0, seed: int = -1)[source]¶

Bases: qiskit.primitives.base.BaseEstimatorV2

DDSIM implementation of Qiskit’s estimator.

The implementation is adapted from Qiskit’s StatevectorEstimator.

property default_precision: float¶: The default precision for expectation-value estimates.

property seed: int¶: The seed for the CircuitSimulator.

run(pubs: Iterable[qiskit.primitives.containers.EstimatorPubLike], *, precision: float | None = None) → PrimitiveJob[qiskit.primitives.containers.PrimitiveResult[qiskit.primitives.containers.PubResult]][source]¶

Estimate expectation values for each provided PUB (primitive unified bloc).

Each PUB is run on the CircuitSimulator.

Parameters:

pubs – An iterable of pub-like objects, such as tuples (circuit, observables) or (circuit, observables, parameter_values).
precision – The target precision for expectation-value estimates. If None, the default precision is used.
