The paper “Experimental validation of photonic boson sampling”, by theorists Ernesto Galvão, IF-UFF PhD Daniel Brod and collaborators has just been published in the journal Nature Photonics. This collaboration involves the experimental quantum optics groups of Fabio Sciarrino (Rome) and Roberto Osellame (Milan). The paper reports the experimental implementation of a restricted type of quantum computer known as a boson sampling machine, which solves a computationally hard problem using multi-photon interference in a complex integrated interferometer. The data analysis relies on recently proposed statistical tests to verify that the computer is working as expected, which is non-trivial to do given the experiment's complexity.
