IBM Scientists Claim They've Achieved 'Quantum Advantage' — and They've Dared Others to Prove Them Wrong
Researchers encoded 70 logical qubits and ran 2,415 two-qubit operations, showing a quantum computation that classical methods could not verify efficiently.
- On Thursday, IBM and the University of Chicago announced a quantum computing milestone demonstrating computations beyond classical simulation reach while providing verified accuracy.
- Researchers addressed the critical challenge of verification by developing a trusted stack to detect errors, as Bill Fefferman, Associate Professor at the University of Chicago, noted it remains a primary obstacle in establishing quantum advantage.
- The team executed 70 logical qubits to run 2,415 logical two-qubit operations and 468 logical T gates in 16.1 minutes, achieving effective logical error rates 10 times lower than physical rates.
- Alongside this milestone, partners Qedma and Algorithmiq announced two additional experiments using IBM Quantum Heron R3 processors, with classical methods eventually failing to converge while quantum results remained consistent.
- IBM released results on the Quantum Advantage Tracker to foster transparency, with researcher Abhinav Kandala noting, "A lot of these problems have been on the tracker for a while now.

Technology giant IBM and international research teams have announced three new studies proving the decisive superiority of quantum processors over classical supercomputers. Scientists achieved results with near-zero error rates, opening the door to a new era in the quantum age.
IBM scientists claim they've achieved 'quantum advantage' — and they've dared others to prove them wrong
Scientists at IBM and partner institutions say they've reached "quantum advantage" in a trio of experiments demonstrating quantum computing capabilities that even the fastest classical supercomputers can't match.In a purported major milestone for quantum computing, the experiments show how these machines could perform useful computational tasks, such as computing chemical reactions, within minutes. By comparison, a supercomputer would take years…
IBM announced that it achieved a quantum advantage by solving a computational problem that existing supercomputers could not solve in just 15 minutes using 70 logical qubits. This research enhanced reliability by introducing error correction technology and is expected to mark a turning point for the commercialization of the technology. However, the academic community is taking a cautious stance, stating that further verification is needed regard…
IBM says quantum computers are getting harder to verify. That's progress.
IBM and its partners say quantum computers are now getting to the point where they can run calculations that can’t be reproduced and verified by using classical methods on today’s computers. While that’s definitely a sign of progress given that useful quantum computers always seem five years away, we are also now getting to the point where we need new ways to check that the quantum computer actually got to the right answer. A result nobody can v…

Phil's Stock WorldIBM quietly cleared a quantum computing hurdle experts doubted
In 2019, Google said it had reached “quantum supremacy.” IBM disputed the claim almost immediately, arguing that a properly tuned supercomputer could nearly match the result within days rather than the ten thousand years Google projected, according to CBS News.…
