Researchers from USC and Johns Hopkins used two IBM Eagle quantum processors to pull off an unconditional, exponential speedup on a classic “guess-the-pattern” puzzle, proving—without assumptions—that quantum machines can now outpace the best classical computers. By squeezing extra performance from hardware with shorter circuits, transpilation, dynamical decoupling, and error-mitigation, the team finally crossed a milestone […]



Summary

Researchers at USC and Johns Hopkins achieved a significant milestone in quantum computing, demonstrating an unconditional, exponential speedup over classical computers. Using IBM’s Eagle quantum processors, they tackled a “guess-the-pattern” puzzle and proved, without relying on any assumptions, that quantum machines can now surpass the capabilities of the most powerful classical computers. This breakthrough was achieved by optimizing hardware performance through techniques like shorter circuits, transpilation, dynamical decoupling, and error mitigation, ultimately crossing a long-awaited threshold in quantum computational power.
