The strong efforts towards the realization of scalable quantum computing are motivated by the promise of super-polynomial speed-up in several computational tasks.A first fundamental step in this route is to provide concrete evidence ofquantum supremacy.Such a regime is obtained when a quantum device is capable of solving a specific problem faster than the best classical hardware.A serious attempt to provide a first demonstration of quantu speed-up with affordable resources is represented by boson sampling [1,2],a non-universal quantum-computational protocol exploiting indistinguishable single photons and linear optical devices.

我七岁上小学,记得我们的教室很大,稀稀落落地坐着二十多名同学,梳辫子的只有七位。老师看了看那怯生生的“半边天”,先让大一些的琴做了学习委员,却选不出文艺委员领唱课前歌,后来慧眼识珠,发现我嗓门儿大又挺大方,便委任了我。 老师们都很愿意做我们的班主任,理由极简单:学生少,操心事少;女生少,操心事更少。所有的班主任也都说我们班女生最友好,总和和气气的。她们却忘了:女孩子天生会掩饰。其实,文艺委员与学
