Google has unveiled a new quantum computer called Willow that excels at a benchmarking problem, but it still isn't clear whether these machines can serve a practical purpose

Alphabet Inc.’s quantum computer needs just five minutes to solve a problem that would take supercomputers around 10 septillion years. Google’s next task: coming up with an actual use for all that theoretical power.

The latest advancements, however, may signal major progress toward building a large-scale quantum computer capable of addressing complex scientific and societal challenges. Unlike
