qiskit.quantum_info.Pauli.insert_paulis

Pauli.insert_paulis(indices=None, paulis=None, pauli_labels=None)

DEPRECATED: Insert or append pauli to the targeted indices.

This function is deprecated. Similar functionality can be obtained using the insert() method.

If indices is None, it means append at the end.

Parameters

• indices (list[int]) – the qubit indices to be inserted

• paulis (Pauli) – the to-be-inserted or appended pauli

• pauli_labels (list[str]) – the to-be-inserted or appended pauli label

Note

the indices refers to the location of original paulis, e.g. if indices = [0, 2], pauli_labels = [‘Z’, ‘I’] and original pauli = ‘ZYXI’ the pauli will be updated to ZY’I’XI’Z’ ‘Z’ and ‘I’ are inserted before the qubit at 0 and 2.

Returns

self

Return type

Pauli

Raises

QiskitError – provide both paulis and pauli_labels at the same time
