 excluding the swapping part to get the right order.
 Here, $$R_m$$ means $$R_\phi$$ with $$\phi = 2 \pi / 2^m$$:

 Again, note how the inputs $$\Ket{x_j}$$ and outputs $$\Ket{k_j}$$ are in the opposite order.
 The complete circuit, including the swapping at the end,
 therefore looks like this:

 For each of the $$n$$ qubits, $$\mathcal{O}(n)$$ gates are applied,
 so overall the QFT algorithm is $$\mathcal{O}(n^2)$$.
