A note on a Claim of Eldar & Hallgren: LLL already solves it

Abstract

In a recent talk of Hallgren on a joint work with Eldar (Sept 21, 2021, Simons Institute), a polynomial-time quantum algorithm for solving BDD in a certain class of lattices was claimed. We show here that known classical (and even, deterministic) polynomial-time algorithms already achieve this result.
