The claim, made in a new scientific paper, is the most serious indication yet that the promise of quantum computers—an emerging but unproven type of machine—is becoming reality, including their potential to solve formerly ungraspable mathematical problems.
Essentially, Google purports to have pulled off a stunt on a quantum computer that no classical machine—not even the world’s most powerful supercomputer—can replicate.
A Google spokesperson declined to confirm the authenticity of the paper and its results. NASA did not respond immediately to a request for comment.
The Google team, which first wrote about their goal in a Nature article two years ago, appears to be more hopeful about the short-term prospects of its findings. “As a result of these developments, quantum computing is transitioning from a research topic to a technology that unlocks new computational capabilities,” the researchers write.
“We are only one creative algorithm away from valuable near-term applications.”"
