IBM Quantum Computer Task Takes 19 Seconds vs 100 Years
Original: IBM's Quantum Computer Completes in 19 Seconds What Could Take a Supercomputer a Century
IBM reports that one of its quantum computers completed a calculation in 19 seconds that would reportedly take a conventional supercomputer around a century to finish. The claim, reported by ScienceAlert, is being circulated as a striking example of quantum advantage, though the details of the task and independent verification remain limited.
Why now: The dramatic speed gap over classical supercomputers feeds ongoing debate about how close quantum computing is to real-world usefulness.
