We give new evidence that quantum computers -- moreover, rudimentary quantum computers built entirely out of linear-optical elements -- cannot be efficiently simulated by classical computers. In particular, we define a model of computation in which identical photons are generated, sent through a linear-optical network, then nonadaptively measured to count the number of photons in each mode. This model is not known or believed to be universal for quantum computation, and indeed, we discuss the… Expand

BosonSampling with Lost Photons
TLDR
It is shown that, if k out of n photons are lost, then BosonSampling cannot sample classically from a distribution that is 1/n^Theta(k)-close to the ideal distribution, unless a $\text{BPP}^{\text{NP}}$ machine can estimate the permanents of Gaussian matrices in $n^{O(k)}$ time. Expand

The Power of Quantum Fourier Sampling
TLDR
This work uses Quantum Fourier Sampling to construct a class of distributions that can be sampled by a quantum computer, and shows a general class of quantumly sampleable distributions each of which is based on an "Efficiently Specifiable" polynomial, for which a classical approximate sampler implies an average-case approximation.

TLDR
It is shown that several simple changes to the axioms of quantum mechanics would let us solve PP-complete problems efficiently, or probabilistic polynomial-time, and implies, as an easy corollary, a celebrated theorem of Beigel, Reingold and Spielman that PP is closed under intersection. Expand
