qiskit.quantum_info.pauli_group

pauli_group(number_of_qubits, case='weight')

DEPRECATED: Return the Pauli group with 4^n elements.

This function is deprecated. Use pauli_basis() for equivalent functionality.

The phases have been removed. case ‘weight’ is ordered by Pauli weights and case ‘tensor’ is ordered by I,X,Y,Z counting lowest qubit fastest.

Parameters

• number_of_qubits (int) – number of qubits
• case (str) – determines ordering of group elements (‘weight’ or ‘tensor’)

Returns

list of Pauli objects

Return type

list

Raises

• QiskitError – case is not ‘weight’ or ‘tensor’
• QiskitError – number_of_qubits is larger than 4
