Google is putting its supreme algorithm to work. In October, the company announced that they had reached quantum supremacy – the point at which a quantum computer can complete a task that no classical computer could practically achieve – with an algorithm that could verify that a given set of numbers was randomly distributed. Now, that algorithm is finding its first practical use as a random number generator.
