qml.pauli.diagonalize_pauli_word

diagonalize_pauli_word(pauli_word)

Transforms the Pauli word to diagonal form in the computational basis.

Parameters:

pauli_word (Operator) – the Pauli word to diagonalize in computational basis

Returns:

the Pauli word diagonalized in the computational basis

Return type:

Operator

Raises:

TypeError – if the input is not a Pauli word, i.e., a Pauli operator, Identity, or tensor products thereof

Example

>>> diagonalize_pauli_word(qml.X('a') @ qml.Y('b') @ qml.Z('c'))
Z('a') @ Z('b') @ Z('c')
