[...] The race is on to create quantum computers that outperform classical machines in specific tasks. Prototypes developed by Google and IBM, headquartered in Mountain View, California, and Armonk, New York, respectively, are approaching the limit of classical computer simulation. In October, scientists at Google announced that a quantum processor working on a specific calculation had achieved such a quantum advantage. Russia is far from this milestone. "We're 5 to 10 years behind," says Fedorov. "But there's a lot of potential here, and we follow very closely what's happening abroad." Poor funding has excluded Russian quantum scientists from competing with Google, says Ilya Besedin, an engineer at the National University of Science and Technology in Moscow.
