Sampler

class Sampler(circuits: Iterable[QuantumCircuit] | QuantumCircuit | None = None, parameters: Iterable[Iterable[Parameter]] | None = None, **kwargs)

Bases: qiskit.primitives.base.base_sampler.BaseSampler

Aer implementation of Sampler class.

Run Options

• shots (None or int) – The number of shots. If None, it calculates the probabilities exactly. Otherwise, it samples from multinomial distributions.

• seed (int) – Set a fixed seed for seed_simulator. If shots is None, this option is ignored.

Note

Precedence of seeding is as follows:

1. seed_simulator in runtime (i.e. in __call__())

2. seed in runtime (i.e. in __call__())

3. seed_simulator of backend_options.

4. default.

Parameters

• circuits – Circuits to be executed.

• parameters – Parameters of each of the quantum circuits. Defaults to [circ.parameters for circ in circuits].

• backend_options – Options passed to AerSimulator.

• transpile_options – Options passed to transpile.

• run_options – Options passed to run.

• skip_transpilation – if True, transpilation is skipped.

Methods

close	Close the session and free resources
run	Run the job of the sampling of bitstrings.
set_options	Set options values for the estimator.
