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

Parâmetros

• 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».

Retorno

The rows of the StabilizerTable in label form.

Tipo de retorno

list or array

Levanta

QiskitError – if stabilizer and destabilizer are both False.
