Experts predict that it will take several years for quantum computing to be put into practical use

Although Google has made a major breakthrough in quantum computing, experts say it will take several years to realize the practical application of quantum computing. Mark Saffman, a professor at the University of Wisconsin-Madison and director of the Wisconsin Quantum Institute, said that error correction is more difficult in quantum computing and requires more hardware resources. Therefore, although Google's progress is important, there are still many challenges to realize the practical application of quantum computing.
