To simulate noisy boson sampling approximating it by only the lower-order multi-boson interferences (e.g., by a smaller number of interfering bosons and classical particles) is very popular idea. I show that the output data from any such classical simulations can be efficiently distinguished from that of the quantum device they try to simulate, even with finite noise in the latter. The distinguishing datasets can be the experimental estimates of some large probabilities, a wide class of such is presented. This is a sequel of \textit{Quantum} \textbf{5}, 423 (2021), where I present more accessible account of the main result enhanced by additional insight on the contribution from the higher-order multi-boson interferences in presence of noise.
翻译:模拟噪音波森取样时,只用较低级的多波孙干扰(例如较少的干扰波孙和古典粒子)来模拟波孙取样,是非常流行的想法。我表明,任何这类古典模拟的输出数据都可以有效地区别于它们试图模拟的量子装置的输出数据,即使后者有有限的噪音。区分的数据集可以是某些大概率的实验估计,可以提供一大类这类数据。这是423(2021年)\ textbf{5}的续集,我在这里介绍了更多关于主要结果的更方便的描述,因为更多了解了在噪音面前的较高级多波孙干扰的作用。
