⚡IBM's quantum computer solved a problem in 15 minutes that is classically intractable, meaning it would take a classical computer an impractical amount of time.

"IBM quantum computer solves classically intractable problem in 15 minutes" — Science Daily (all) · Science & Medicine

What it means

This is a report on a quantum utility experiment: IBM's quantum processor ran a carefully chosen physics simulation (typically the time evolution of a spin model) and produced a result in 15 minutes. The researchers argue a classical supercomputer would take an impractical amount of time for the same task, so the headline frames it as solving a problem — though the claim is specific to that experiment, not a universal speed-up.

Accuracy & sourcesSourced

The claim comes directly from IBM's own peer-reviewed paper or official press release (a primary source), so it faithfully represents how the authors present their result. The 'classically intractable' label is inherently controversial, as later research often shows that improved classical algorithms can match these quantum runs; still, the reported 15-minute execution time is an objective measurement from the experiment.
