find_closest_unitary_opmx(operation_mx, op_basis='pp')

Find the closest (in fidelity) unitary superoperator to operation_mx.

Finds the closest operation matrix (by maximizing fidelity) to operation_mx that describes a unitary quantum gate.

Parameters:

• operation_mx (numpy array) – The operation matrix to act on.

• op_basis (Basis | str)

Returns:

The resulting closest unitary operation matrix.

Return type:

numpy array
