- Clifford.to_labels(array=False, mode='B')[source]¶
Convert a Clifford to a list Pauli (de)stabilizer string labels.
For large Clifford converting using the
array=Truekwarg will be more efficient since it allocates memory for the full Numpy array of labels in advance.Table 2 Stabilizer Representations¶ Label

- Paramètres
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 ».
- Renvoie
The rows of the StabilizerTable in label form.
- Type renvoyé
list or array
- Lève
QiskitError – if stabilizer and destabilizer are both False.
