Calibration experiments now represent all two-qubit gates by default (previously this was just $\mathrm{C}X$ and $\mathrm{C}Z$ gates.) +2. When running `calibrator.run(log=True)` you will now find results from your PEC pretty-printed alongside any ZNE experiments. + +#### Installation + +Our core dependencies (NumPy, Cirq, SciPy) are now less tightly specified which means easier installs for users! + +#### Robust Shadow Estimation + +@Min-Li has been hard at work bringing shadows to Mitiq. +The `shadows` module is not quite ready for use, but you can get a sneak peak of what's to come in the Classical Shadows section of our [API-doc](https://mitiq.readthedocs.io/en/latest/apidoc.html#classical-shadows). + +### All changes + +- Fix docstring in qse.py (#1944) [@misty-w] +- Add QSE to API-doc (#1938) [@natestemen] +- fix asv benchmarks (#1937) [@natestemen] +- [Classical Shadows 1] classical postprocessing (#1908) [@min-li] +- Add Calibration logging for PEC (#1873) [@misty-w] +- [Classical Shadows 1] utils for shadows and unit test (#1907) [@min-li] +- Clean up types (#1825) [@natestemen] +- Relax test condition for `test_execute_with_pauli_twirling` (#1931) [@misty-w] +- loosen remaining core dependency versions (#1917) [@natestemen] +- [Classical Shadows] quantum processing and test (#1906) [@min-li] +- Make PEC calibration support all multi-qubit-gate (#1881) [@YuNariai] +- Implements high-level functions for QSE (#1902) [@bubakazouba] +- Temporary fix for documentation problem (#1927) [@andreamari] +- Adding layerwise folding as tutorial to mitiq.
