Google's Quantum chip claims 13,000x speed advantage over supercomputers

"Google Quantum AI has demonstrated what it describes as a verifiable quantum advantage - running a new algorithm on quantum hardware that outperforms classical supercomputers by a factor of 13,000. The breakthrough, announced on Wednesday, marks the first time a quantum computer has executed a verifiable algorithm with real-world applications, potentially accelerating enterprise workloads in computational chemistry, molecular modeling, and materials engineering that are currently constrained by classical computing limitations."

"The achievement centers on Google's Willow quantum chip, a 105-qubit superconducting processor, executing what the company calls its Quantum Echoes algorithm, technically an out-of-time-order correlator (OTOC), a method for measuring how disturbances spread through quantum systems. "This is the first time in history that any quantum computer has successfully run a verifiable algorithm that surpasses the ability of supercomputers," Google said in a statement announcing the breakthrough, which was also published in Nature."

Google Quantum AI demonstrated a verifiable quantum advantage by running a Quantum Echoes out-of-time-order correlator (OTOC) algorithm on the Willow 105-qubit superconducting processor. The run produced a 13,000x performance advantage relative to the best classical algorithm on one of the world's fastest supercomputers, though the specific supercomputer was not identified. OTOC measures how disturbances spread through quantum systems and has potential applications in computational chemistry, molecular modeling, and materials engineering. Quantum verifiability allows results to be repeated on the same-caliber quantum machines to confirm outcomes, marking a shift from abstract benchmarks toward practical, reproducible quantum computing for real-world workloads.
