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 3 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"	\([0, 1]\)	\(\begin{bmatrix} 1 & 0 \\ 0 & -1 \end{bmatrix}\)

Parameter

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

Rückgabe

The rows of the PauliList in label form.
