Journal ArticleDOI
Integrated multimode interferometers with arbitrary designs for photonic boson sampling
Andrea Crespi,Roberto Osellame,Roberta Ramponi,Daniel J. Brod,Ernesto F. Galvão,Nicolò Spagnolo,Chiara Vitelli,Chiara Vitelli,Enrico Maiorino,Paolo Mataloni,Fabio Sciarrino +10 more
TL;DR: In this article, a five-mode integrated interferometer containing three-dimensional S-bent waveguides was used to sample three single photons and the probability ratios of all events were measured.
Journal ArticleDOI

Nicolò Spagnolo,Chiara Vitelli,Chiara Vitelli,Marco Bentivegna,Daniel J. Brod,Andrea Crespi,Fulvio Flamini,Sandro Giacomini,Giorgio Milani,Roberta Ramponi,Paolo Mataloni,Roberto Osellame,Ernesto F. Galvão,Fabio Sciarrino +13 more
TL;DR: In this paper, the Aaronson-Arkhipov test is used to distinguish the AARonson-Arkinov test from uniformly drawn samples for boson-sampling experiments.
Journal ArticleDOI
Experimental scattershot boson sampling
Marco Bentivegna,Nicolò Spagnolo,Chiara Vitelli,Chiara Vitelli,Fulvio Flamini,Niko Viggianiello,Ludovico Latmiral,Paolo Mataloni,Daniel J. Brod,Ernesto F. Galvão,Andrea Crespi,Andrea Crespi,Roberta Ramponi,Roberta Ramponi,Roberto Osellame,Roberto Osellame,Fabio Sciarrino +16 more
TL;DR: The first scattershot boson sampling experiments are reported, where six different photon-pair sources are coupled to integrated photonic circuits, providing strong evidence that the photonic quantum simulator works as expected.
Journal ArticleDOI
Discrete Wigner functions and quantum computational speedup
TL;DR: Gibbons et al. as discussed by the authors characterized the convex hull of stabilizer states and showed that negativity of Wigner functions is necessary for exponential speedup in pure-state quantum computation.
Journal ArticleDOI
Photonic implementation of boson sampling: a review
Daniel J. Brod,Ernesto F. Galvão,Andrea Crespi,Roberto Osellame,Nicolò Spagnolo,Fabio Sciarrino +5 more
TL;DR: This work reviews recent advances and discusses the future application of photonic boson sampling devices beyond the original theoretical scope, describing both the technological improvements achieved and the future challenges.
