pyquil.paulis.check_commutation(pauli_list, pauli_two)

Check if commuting a PauliTerm commutes with a list of other terms by natural calculation. Uses the result in Section 3 of arXiv:1405.5749v2, modified slightly here to check for the number of anti-coincidences (which must always be even for commuting PauliTerms) instead of the no. of coincidences, as in the paper.

Parameters

• pauli_list (Sequence[PauliTerm]) – A list of PauliTerm objects

• pauli_two_term – A PauliTerm object

Return type

bool

Returns

True if pauli_two object commutes with pauli_list, False otherwise
