Fine-Grained Complexity for Quantum Problems from Size-Preserving Circuit-to-Hamiltonian Constructions
Nai-Hui Chia, Atsuya Hasegawa, François Le Gall +1
The local Hamiltonian (LH) problem is the canonical -complete problem introduced by Kitaev. In this paper, we show its hardness in a very strong sense: we show that t…
