Check coverage before comparing two weeks
This analysis shows why source coverage, publication dates, and indexing delays must be checked before a weekly increase is interpreted as growth.
QUANTUM COMPUTING & INFORMATION
Research analysis
Evidence-led comparisons of the observatory’s corpus, with scope and uncertainty made explicit.
What linked versions change in a weekly count
The observatory keeps source records separate for provenance while grouping only explicitly connected publication versions for research counts.
Why quantum topic counts overlap
Multi-label topic rules support discovery, but their totals cannot be added or interpreted as exclusive market shares.
Citation counts are context, not a ranking
Citation metadata can help readers orient themselves, but it cannot fairly rank new work or replace reading the evidence.
