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

The hybrid GHZ-BSM routing strategy outperforms BSM routing in square grid networks. In other networks, however, more sophisticated adaptations using global information are required.

C2weakest assumption

The assumption that GHZ measurement success probabilities are fixed, known in advance, and uniform across links, and that the chosen network models (square grids, Waxman, scale-free, SURFnet) capture the dominant loss and connectivity features of real quantum channels without additional hardware-specific effects.

C3one line summary

A hybrid GHZ-BSM routing strategy outperforms pure BSM routing in square grid quantum networks but requires global-information adaptations to beat BSM in complex topologies such as Waxman, scale-free, and SURFnet.
