It was all over the news a few days ago that Google had reached the quantum supremacy in an experiment, where a quantum processor proved that the figures pumped out by a random number generator were indeed random. This task took 3 minutes 20 seconds (200 seconds) for the quantum processor and according to the estimations, the most powerful classical computer would need approx. 10,000 years for completing the same task.
Of course, there is a lot of uncertainty around this news (actually, it's more a leak than an actual announcement), but at the same time it shows the advent of a very exciting era in computing. (The original study "Quantum Supremacy Using a Programmable Superconducting Processor" was available at NASA's website for a short period of time.)
Besides the fact that quantum computing, by its incredible computing capabilities, may open a new era for development of pharmaceuticals, artificial-intelligence applications, etc., it raises a number of questions, some of which are very important also for data protection.
