Changelog#

Version 0.9.0#

  • Migrate from index based Z-observables to Qiskits SparsePauliOps

    • The observables parameter for all functions now takes a list of Qiskits SparsePauliOp objects instead of lists of qubit indices.

    • This allows for more general observables to be calculated, including multi-qubit observables and observables with different Pauli operators.

    • Check documentation for details on how to use.

Version 0.8.0#

  • Support for cutting 2 qubit gates

    • Added cutGate function for cutting 2 qubit gates directly.

    • Cutting done by transpiling the 2 qubit gate into a cut CZ gate with appropriate basis changes.

    • For non CZ family gates this results in suboptimal decompositions. More optimised decompositions will be added in future releases.

    • Check documentation for details on how to use.

Version 0.7.0#

  • Rework transpilation workflow
    • Transpilation now done per subcircuit instead of per experiment circuit.

      • Per experiment transpilation still provided for more control.

      • Users can of course still manually transpile circuits before passing to QCut.

    • This greatly reduces the number of transpilation calls needed, improving performance.

    • Check documentation for details on how to use.

  • Bug fixes

Version 0.6.0#

  • Support cutting CZ gates

    • Added support for cutting CZ gates in addition wire cuts.

    • Check documentation for details on how to use.

  • Added automatic cut finding feature

    • Added QCutFind module for automatically finding good cut locations in a circuit.

    • Check documentation for details on how to use.

  • Bug fixes

  • Drop windows support for the time being due to METIS issues

    • Windows users should use WSL

Version 0.3.0#

  • Support for IQM Qiskit 17.8

    • Added support for IQM Qiskit 17.8.

  • Removed built in mitigate flag

  • Bug fixes

  • Remove old two qubit gate CutWire operation

    • Users using the old method can consult documentation for migration help

Version 0.2.4#

  • Bugfix for incorrect partitioning for cases where there are multipe cuts on a single wire

Version 0.2.3#

  • Major optimisation on _move_to_new_wire method.

    • Old version took around 11s for a random circuit with depth of 50 and 50 qubits.

    • New version takes around 0.2s for the same circuit.

Version 0.2.2#

  • Bugfix for array overflow in get_experiment_circuits

Version 0.2.1#

  • Hotfix for incorrect version of qiskit-aer in pyproject.toml.

  • Fix pypi workflow

Version 0.2.0#

  • Single qubit cut gate now the default cut method

    • Greatly simplifies placing cuts.

    • Old two qubit gate deprecated and will be removed soon.

    • Check out documentation for migration help.

Version 0.1.3#

  • Hotfix for source files not included in pypi build.

    • 0.1.0 - 0.1.2 not installable.

Version 0.1.2#

  • Add Qiskit 1.0 support.

    • Supported versions now >= 0.45.3, < 1.2.

    • No worflow changes. No migration required.

    • Compatible with qiskit-iqm 13.15

  • Add Python 3.11 support.

    • Supported versions now >= 3.9, < 3.12.

  • Fix bug in _get_bounds() method.

  • Use pickle.loads(pickle.dumps()) instead of deepcopy() in _get_experiment_circuits().

    • Slight performance improvement.

  • Revert back to vx.x.x versioning scheme.

Version 0.1.1#

  • Code quality improvements:

    • Move to pyproject.toml. Contents of ruff.toml and setup.py now live in pyproject.toml.

    • Relative imports are now absolute imports.

    • All images are now located under the _static folder.

  • Added Github workflows:

    • Added github actions workflows for building the documentation and testing that the documentation can be built.

    • Added github actions workflows for testing the code.

    • Added github actions workflows for publishing to pypi.

    • Added github actions workflows for linting.

  • Revamped documentation:

    • Documentation now uses the Book theme.

    • Fixed all warnings from sphinx when building the documentation.

    • Fixed spelling mistakes.

    • Added a new page for the changelog.

  • README now contains the information to build the docs.

  • Change versioning scheme to “x.x.x” instead of “vx.x.x”.

Version 0.1.0#

  • First stable release
