Update SamplerV2 and EstimatorV2 to be compatible with those of Qiskit 1.1 #2150

Closed t-imamichi closed 2 weeks ago

t-imamichi commented 1 month ago

Summary

Update SamplerV2 and EstimatorV2 to be compatible with Qiskit 1.1

SamplerV2 returns SamplerPubResult
They use DataBin class directly and stop using make_data_bin.
Removed np.random.Generator as seed because AerSimulator.run does not support it. (I think it never worked yet)

This PR updates the required Qiskit version to 1.1.0 because the above changes require Qiskit 1.1.

Note

SamplerV2 is based on BackendSamplerV2 of Qiskit.
EstimatorV2 is based on StatevectorEstimator of Qiskit because EstimatorV2 directly computes expectation values with save_expectation_value instruction instead of appending Pauli pre-rotations.
