DESCRIPTION:Barry Sanders\, University of Calgary\n\nThe BosonSampling Prob
lem is to sample output photon-coincidence probabilities given vacuum and
single-photon inputs to a passive interferometer with more channels than p
hotons. This problem is classically hard to simulate as these probabilitie
s are weighted by computationally hard permanents of sub-matrices of the i
nterferometer transition matrix yet efficient to execute quantumly. Our in
novation [1\,2] introduces distinguishability between photons by controlli
ng arrival times of otherwise identical photons in order to test the model
\, assess sampling errors and generalize BosonSampling beyond permanent-we
ighted to immanant-weighted probabilities.\n
