So about that Quantum Lattice Thing: Rebuttal to “Exact Coset Sampling for Quantum Lattice Algorithms” (Daniel Apon) ia.cr/2025/1945
Abstract. In this note we identify major issues with “Exact Coset Sampling for Quantum Lattice Algorithms” by Zhang. The issues include: • in the first version, the proposed algorithm requires foreknowledge of the answer to compute the answer; • in the latest version, the proposed algorithm displays basic misunderstandings of quantum mechanics. We believe the existence of these issues refute the author’s claims.
