SamplerSimulation#

class iqm.qaoa.backends.SamplerSimulation(simulator=AerSimulator('aer_simulator_statevector'), transpiler=None)[source]#

Bases: SamplerBackend

A sampler that simulates the QAOA circuit in qiskit.

Currently the only simulator we use is the AerSimulator, but SamplerSimulation is defined to allow the use of other simulators too. Some simulators may need the circuit to be transpiled, so optionally a string describing the transpiler can be provided.

Parameters:

  • simulator (BackendV2) – A simulator, (currently) assumed to be an object of class AerSimulator.

  • transpiler (str | None) – A string describing the transpilation method to use (if applicable).

Methods

sample(qaoa_object, shots)

Samples from the QAOA using a simulation.
sample(qaoa_object, shots)[source]#

Samples from the QAOA using a simulation.

Parameters:

  • qaoa_object (QAOA) – The QAOA object, to be sampled from.

  • shots (int) – The number of samples (measurements) to take.

Returns:

A dictionary whose keys are the measured bitstrings and values their frequencies in the results.

Return type:

dict[str, int]
