IBM unveils three new demonstrations claiming quantum advantage on noisy hardware

IBM launched a new quantum-advantage tracker, presenting three latest experiments that it claims demonstrate a clear edge over classical computers on today’s noisy quantum hardware. Jay Gambetta explained that achieving trustworthy results without classical verification is a major milestone. Each experiment employs a distinct strategy to mitigate errors and confirm the output’s correctness.

Although none of the results are ready for real-world applications, they indicate that the technology is moving in the right direction. The announcement also underscored ongoing challenges, such as the difficulty of validating quantum outputs and the risk that improved classical algorithms could narrow the gap. IBM hopes the tracker will help the community gauge genuine quantum progress.
