qiskit.quantum_info.pauli_group

pauli_group(number_of_qubits, case='weight')

Return the Pauli group with 4^n elements.

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.

パラメータ

• number_of_qubits (int) – number of qubits

• case (str) – determines ordering of group elements (『weight』 or 『tensor』)

戻り値

list of Pauli objects

戻り値の型

list

例外

• QiskitError – case is not 『weight』 or 『tensor』

• QiskitError – number_of_qubits is larger than 4
