Seven finalist teams were selected in December 2025 and are in Phase II as of August 2026; winners are due Spring 2027, with no prize yet claimed.
The question, scope, and sources behind this Registry record.
Design and analyze a quantum algorithm with a credible, judged path to genuine quantum computational advantage on a real-world problem (e.g. drug discovery, climate modeling, fusion energy, or materials science), as evaluated against classical approaches by an independent judging panel.
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.
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.

The frontier as it changed over time.
Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
