The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We establish a necessary and sufficient condition for an incoherent state preserving CPTP map E to be a particular type of Strictly Incoherent Operation (SIO).

C2weakest assumption

The assumption that the catalysis pre-processing step can be implemented with an auxiliary state without introducing additional decoherence or resource costs that would negate the coherence gain, which is implicit in the setup but not detailed in the abstract.

C3one line summary

Catalysis can improve the coherence fraction of states after noisy quantum channels under specific conditions, and a new necessary and sufficient condition characterizes strictly incoherent operations among incoherent-state-preserving CPTP maps.
