* added skeleton BaseXPPauli and xp_pauli_rep * fixed formatting and lint warnings in xp * made changes to XP documentation as per feedback * changed variable name from N to precision in base_xp_pauli * changed np.int8 to np.int64 in base_xp_pauli
* Change from "stabilizer" to "propagator" for speed. (#245) Co-authored-by: grace-harper-ibm <[email protected]> Co-authored-by: Iskandar Sitdikov <[email protected]> Co-authored-by: Drew Vandeth <[email protected]> * retworkx to rustworkx (#265) * 260 decoding graph fix (#261) * move code block to avoid issue * Update test_codes.py * add test for dg * removed unused variable Co-authored-by: grace-harper-ibm <[email protected]> * fix for warning by casting array_ to numpy array with dtype=object in squeeze (#248) Co-authored-by: grace-harper-ibm <[email protected]> * Use PyMatching 0.7.0 (#278) * Update requirements.txt To require previous pymatching version * PyMatching requirements Gave PyMatching range so that pip install has more wiggle room for managing dependency reqs. * PyMatching requirements update Co-authored-by: grace-harper-ibm <[email protected]> * Make qiskit-qec compatible with pymatching v2 (#280) * Add !=2.0.0 to pymatching in requirements.txt, fix a test that fails for pymatching >v2.0.0 * Remove edges, instead of assigning large weights Co-authored-by: Oscar Higgott <[email protected]> Co-authored-by: grace-harper-ibm <[email protected]> Co-authored-by: Andrew Cross <[email protected]> Co-authored-by: Iskandar Sitdikov <[email protected]> Co-authored-by: Drew Vandeth <[email protected]> Co-authored-by: James Wootton <[email protected]> Co-authored-by: Dhruv Bhatnagar <[email protected]> Co-authored-by: oscarhiggott <[email protected]> Co-authored-by: Oscar Higgott <[email protected]>

* added xp_pauli class * added functions for random xp, precision rescaling, unique vector * added test_xp_pauli and simple test * added weight / XPDistance function * added XPisDiag function as is_diagonal * coded XPD (antisymmetric operator) and refactored * added XPPower * added XP multiplication * added XP degree function * added dummy XPPauliList * added test for XPPauliList init, and function in xp_pauli_rep * added some tests for XPPauliList and upgraded some functions to work for XPPauliList * cleaned lint and black * renamed _num_paulis to _num_xppaulis * added missing truncate variable * resolved weight todo * revert precision from list to integer in BaseXPPauli * added type hints * removed array as allowed precision from assertion and updated tests * acknowledged XPF paper on top of BaseXPPauli... files * added acknowledgement note in individual methods of BaseXPPauli... * added see also in BaseXPPauli... methods * changed assertion to if...raise and moved check to higher level method * changed assertion to if...raise * added docstrings for BaseXPPauli... methods * XPF: 1. added examples in docstring 2. updated 1 method to work for xppaulilist 3. added test * added example and minor change for random_xppauli * added check in rescale_precision * added remaining tests for XPPauliList for currently coded functions * cleaned black and lint

* Modify antisymmetric_op based on Issue 299 and change use of compose in tests * Add inverse method (to base_xp_pauli, xp_pauli, and xp_pauli_list) and tests * Add conjugate method and tests * Add commutator method and tests * Add fundamental_phase method and tests Also modify power method such that each operator in an XPPauliList can be raised to different powers * Add reset_eigenvalue method and tests * Linting cleanup * Fix small error in reset_eigenvalue method * Add "See also" in docstrings * Modify `power` based on comments The `power` method now accepts int, list, or np.ndarray as input. If an int is provided, all XP operators in an XPPauliList would be raised to the same power. * Revert change in precision check * Add docstrings for x, _x, z, _z * Add warnings and inplace option for `rescale_precision()` * Add inplace option for `reset_eigenvalue()`
* beginning to add basic stuff to xp_pauli_rep * implemented xp_symplectic2str basic functionality, added tests * Implemented changes discussed with Ruihao about exponent of P * Added documentation, examples, type hints
