Regarding Lukin’s experiment - which is very interesting and high quality - in most instances it can be simulated by existing classical methods (matrix product states / DMRG being a key example). This does not detract from the importance of realizing the same system experimentally at all. But it does prevent it from realizing a gap between classical and quantum computing.
