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

if a certain work distribution shows negativity asymptotically in the limit of a large number of cells and in a certain time interval, then we surely get a quantum advantage in the charging process.

C2weakest assumption

The work exhibits statistics that can be represented by a quasiprobability in the presence of initial quantum coherence in the energy basis (stated in the abstract as the general setting).

C3one line summary

Negativity in the large-N limit of work quasiprobability distributions guarantees quantum advantage in charging quantum batteries.
