IBM quantum computer completes task in 19 seconds
Original: IBM's Quantum Computer Completes in 19 Seconds What Could Take a Supercomputer a Century
IBM says one of its quantum computers finished a calculation in 19 seconds that it estimates would take a conventional supercomputer around a century to complete. The claim, reported by ScienceAlert, is being circulated as a striking illustration of quantum advantage, though independent verification of the benchmark and how it was measured has not yet been established.
Why now: A dramatic quantum-versus-classical performance claim naturally draws attention to how close practical quantum computing is.
