In the framework

What the capability covers and what it leaves to others, and the indicators it will be measured by.

Bounds

Covers the cryptographic capability and the migration capacity; the systems being migrated belong to their own domains, and the migration's progress is this capability's deploy-layer indicator. Retained in this group on the logic that the threat, the timeline and the national programmes that own the response are quantum ones.

Lineage

Carried from v0.0 with the same identifier; recast from algorithm definition to the standardisation-and-migration capacity, which is where states now differ.

Indicators

  • standardised algorithms authored or co-authoredPending
  • national migration mandates issuedPending
  • share of government systems migratedPending
