circuit_knitting.utils.simulation.ExactSampler

class ExactSampler(*, options=None)

Sampler which returns exact probabilities for each possible outcome.

This sampler supports:

• all unitary gates

• projective measurements, anywhere in the circuit

• reset operations, anywhere in the circuit

• some (or all) classical bits can remain unused

• classical bits can be written more than once

The samplers provided by qiskit.primitives and qiskit_aer.primitives do not currently support all of the above functionality. Related upstream issues:

• https://github.com/Qiskit/qiskit-terra/issues/9657

• https://github.com/Qiskit/qiskit-aer/issues/1810

• https://github.com/Qiskit/qiskit-aer/issues/1811

Parameters:

options (dict | None) – Default options.

__init__(*, options=None)

Parameters:

options (dict | None) – Default options.

Methods

__init__(*[, options])	type options: dict | None
run(circuits[, parameter_values])	Run the job of the sampling of bitstrings.
set_options(**fields)	Set options values for the estimator.

Attributes

options

Return options values for the estimator.
