qat.quops.math_util.make_pauli_matrix_basis(nqbits)

Construct the Pauli basis (including identity) for \(N\) qubits

\[\sigma_{I_1}^{(1)} \otimes \sigma_{I_2}^{(2)} \otimes \ldots \otimes \sigma_{I_N}^{(N)}\]

with \(\sigma_{I}\) respectively denoting the identity and the X, Y, Z Pauli matrices.

Parameters

nqbits (int) – number of qubits \(N\)

Returns

list of Pauli matrices

Return type

list<np.ndarray>
