The passage around this formula
The simulation will therefore use QFI as a diagnostic, not as the definition of publicity. For each fragment it will calculate a local quantum Fisher matrix where feasible, optimize or approximate a covariant measurement for the global loss, and directly estimate . A fragment with high local QFI but multiple globally ambiguous orientations may fail the operational threshold. Conversely, a fragment can pass a coarse angular threshold without saturating the local bound.
