Google Claims Quantum Supremacy: 3 Minutes 20 Seconds vs 10 000 Years on Summit Supercomputer

According to the UK Financial Times, Google’s quantum research team reported that their 53‑qubit processor, codenamed Sycamore, performed a specific random‑circuit sampling task in 3 minutes 20 seconds—a calculation that would require about 10 000 years on the Summit supercomputer, the fastest classical machine today.

The experiment is described as the first demonstration of "quantum supremacy" (or quantum advantage), meaning a quantum device solves a problem that is infeasible for any classical computer, even though the task has limited practical use.

Google’s team, led by physicist John Martinis, highlighted that the speedup is dramatic and predicts a future "double‑exponential" growth in quantum‑computing capability, potentially outpacing Moore’s law.

Experts note that while the result is a significant scientific milestone, quantum computers are still far from solving real‑world problems; current devices can only execute highly specialized, one‑off calculations.

Industry observers, such as Riverlane founder Steve Brierley, called the achievement a historic breakthrough, whereas some commentators caution against over‑hyping its immediate impact on fields like cryptography, AI, or materials science.

The original paper briefly appeared on NASA’s website before disappearing, sparking online jokes and speculation about the paper’s existence, but Google has not commented further.
