qiskit.quantum_info.Clifford.to_labels

Clifford.to_labels(array=False, mode='B')

Convert a Clifford to a list Pauli (de)stabilizer string labels.

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

Table 2 Stabilizer Representations

Label	Phase	Symplectic	Matrix	Pauli
"+I"	0	\([0, 0]\)	\(\begin{bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix}\)	\(I\)
"-I"	1	\([0, 0]\)	\(\begin{bmatrix} -1 & 0 \\ 0 & -1 \end{bmatrix}\)	\(-I\)
"X"	0	\([1, 0]\)	\(\begin{bmatrix} 0 & 1 \\ 1 & 0 \end{bmatrix}\)	\(X\)
"-X"	1	\([1, 0]\)	\(\begin{bmatrix} 0 & -1 \\ -1 & 0 \end{bmatrix}\)	\(-X\)
"Y"	0	\([1, 1]\)	\(\begin{bmatrix} 0 & 1 \\ -1 & 0 \end{bmatrix}\)	\(iY\)
"-Y"	1	\([1, 1]\)	\(\begin{bmatrix} 0 & -1 \\ 1 & 0 \end{bmatrix}\)	\(-iY\)
"Z"	0	\([0, 1]\)	\(\begin{bmatrix} 1 & 0 \\ 0 & -1 \end{bmatrix}\)	\(Z\)
"-Z"	1	\([0, 1]\)	\(\begin{bmatrix} -1 & 0 \\ 0 & 1 \end{bmatrix}\)	\(-Z\)

매개변수

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

• mode (Literal["S", "D", "B"]) – return both stabilizer and destablizer if 《B》, return only stabilizer if 《S》 and return only destablizer if 《D》.
