Limits RegistryPUBLIC RECORD
Limits RegistryIn October 2019, Google's Sycamore processor performed a specific random-circuit-sampling task in about 200 seconds that Google's team estimated would take the Summit supercomputer roughly 10,000 years, marking the first published claim of 'quantum computational supremacy' in a peer-reviewed journal (Nature). The classical-time estimate was later disputed and substantially revised down by IBM and other groups using improved classical simulation methods, though the original claim remains the landmark first announcement.

The estimated classical-supercomputer time originally claimed by Google to reproduce the random-circuit-sampling task performed in 200 seconds by its 53-qubit Sycamore superconducting quantum processor.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
