Particularly, a boson sampling experiment with a moderate number of photons becomes intractable even for the most powerful classical computers, and will lead to \"quantum supremacy\". Scaling up from small-scale experiments requires highly indistinguishable single photons, which may be prohibited for many physical systems.
