rqutils.paulis.general.paulis

rqutils.paulis.general.paulis(dim: int | integer | Sequence[int | integer], sparse: bool = False) → NDArray[complex128] | tuple[csr_array]

Return an array of generalized Pauli matrices or matrix products of given dimension(s).

Parameters:

• dim – Dimension(s) of the Pauli matrices.

• sparse – Whether to return the matrices as an array (dtype=object) of CSR arrays.

Returns:

An array of Pauli (product) matrices as an array. For dim=(d1, d2, …), the shape of the array is (d1**2, d2**2, …, d1*d2*…, d1*d2*…).
