qiskit.quantum_info.PauliList.to_labels

PauliList.to_labels(array=False)

Convert a PauliList to a list Pauli string labels.

For large PauliLists converting using the array=True kwarg will be more efficient since it allocates memory for the full Numpy array of labels in advance.

Table 8 Pauli Representations

Label	Symplectic	Matrix
"I"	$[0, 0]$	$\begin{bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix}$
"X"	$[1, 0]$	$\begin{bmatrix} 0 & 1 \\ 1 & 0 \end{bmatrix}$
"Y"	$[1, 1]$	$\begin{bmatrix} 0 & -i \\ i & 0 \end{bmatrix}$
"Z"	$[0, 1]$	$\begin{bmatrix} 1 & 0 \\ 0 & -1 \end{bmatrix}$

Parameters

array (bool) – return a Numpy array if True, otherwise return a list (Default: False).

Returns

The rows of the PauliList in label form.

Return type

list or array
