Quantum computers, if they are adapted for a use outside laboratories, can be used to achieve breakthroughs in such spheres as machine learning, materials science and chemistry, but it can also pose a security threat, since it's widely considered that such computers will be able to crack any encryption in no time. reports citing Sputnik.

A group of researchers from Google AI Quantum has published a paper, confirming late September reports that the company successfully archived so-called "quantum supremacy" - using a computer based on quantum principles to solve a task deemed impossible for regular machines. Their research was published in the scientific journal Nature.

The experimental task, described in the paper, corresponds to one reportedly described in a now deleted post on the NASA website that teased Google's achievement. The company's quantum computer managed to verify if a pseudo-random numbers generator produces truly random numbers. The researchers indicated that this computer's capability already has a practical use in generating "certifiable random numbers".

The authors of the paper calculated that a supercomputer based on classic principles would take 10,000 years to complete this task, whilst its quantum "brother" only took 3 minutes and 20 seconds, which is 1.5 billion times faster.
