qml.grouping.are_pauli_words_qwc

are_pauli_words_qwc(lst_pauli_words)[source]

Given a list of observables assumed to be valid Pauli words, determine if they are pairwise qubit-wise commuting.

This implementation has time complexity ~ O(m * n) for m Pauli words and n wires, where n is the number of distinct wire labels used to represent the Pauli words.

Parameters

lst_pauli_words (list[Observable]) – List of observables (assumed to be valid Pauli words).

Returns

True if they are all qubit-wise commuting, false otherwise.

Return type

(bool)
