Classical computation has been at the centre of human life in the last fifty years, contributing to the evolution of our life style, from basic calculations to games, phones, very complex artificial networks and so on and so forth. Unfortunately, besides the wonders, there are problems that computers cannot solve so easily, as factoring big numbers or simulate phenomena belonging to the microscopical realm. Here the idea of the quantum computer. Surely you have noticed that inserting the word quantum in any context is very cool. But why? Well, because exploiting quantum properties there is a speed-up in computation with respect its classical counterpart. Lucky us, it is very difficult to reach this goal, therefore, the real question is: how can I find real evidences of this quantum supremacy? A possible answer comes from the Boson Sampling problem. Injecting indistinguishable photons into a complex interferometer and measuring the outputs, we could show the real advantage of quantum computation and open the way to a new quantum technological era. Or it is just a pretext to invoke the word “quantum” in ordinary life.
