The question, scope, and sources behind this Registry record.
Bound the unassisted asymptotic quantum capacity of the memoryless Pauli depolarizing channel applying each nonidentity Pauli with probability p/3.
Current frontiers derived from accepted Claims.
Assertions tied to evidence, attribution, and review.
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.
