Abstract:We present a quantum attack on ML-KEM and related 2-power cyclotomic lattice schemes. Combining with Parts I-III, we provide an algorithm and verify the resulting approximation factor satisfies $\gamma \le 21

Comments:<br>24 pages. You have to read previous three parts (Parts I, II, III) before understanding the details of this part. You may test if you want to or you have question
