Achieving quantum supremacy with sparse and noisy commuting
... and substantially simpler than the usual models.) Crucially, this noise-tolerance can be combined with the notion of approximation used in [11] to show that, under the same complexity assumptions as [11], it is hard for a classical algorithm to approximately sample from the noisy output distribution ...
