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

パラメータ

• 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」.

戻り値

The rows of the StabilizerTable in label form.

戻り値の型

list or array

例外

QiskitError – if stabilizer and destabilizer are both False.
