Qiskit addon utilities release notes

0.3.0

New Features

• Added a new sub-package, qiskit_addon_utils.exp_vals, containing functions for calculating expectation values from the outputs of Qiskit Runtime’s new Executor primitive prototype. This includes:

  • qiskit_addon_utils.exp_vals.executor_expectation_values() for expectation value calculation
  • qiskit_addon_utils.exp_vals.get_measurement_bases() for identifying a minimal set of measurement bases to cover all terms in the observable.
  • qiskit_addon_utils.exp_vals.map_observable_isa_to_canonical(), qiskit_addon_utils.exp_vals.map_observable_virtual_to_canonical(), and qiskit_addon_utils.exp_vals.map_observable_isa_to_virtual() for transforming the qubit order of Pauli observables.

• Added two new functions to the qiskit_addon_utils.noise_management sub-package:

  • qiskit_addon_utils.noise_management.trex_factors() for calculating TREX readout error mitigation scaling factors
  • qiskit_addon_utils.noise_management.gamma_from_noisy_boxes() for calculating the gamma factor for a given circuit and noise model.

0.2.0

New Features

• Add the transpiler passes required to pre-process the circuits, as well as the PostSelector and PostSelectionSummary objects required to post-process the results.

Upgrade Notes

• This addition requires bumping the version of Qiskit SDK to at least 2.0.

• This package is now compatible with Qiskit SDK 2.0.

Bug Fixes

• Support circuits that include classical bits when slicing a circuit by gate types. See #115 <https://github.com/Qiskit/qiskit-addon-utils/issues/115> for details.

Other Notes

• This release adds support for Python 3.13. No code changes were necessary, so older releases are expected to work on Python 3.13 too.

0.1.0

Upgrade Notes

• The keyword argument include_slice_barriers of combine_slices() has been renamed to include_barriers.
