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

Coherent Hamiltonian simulation provides the clearest formal case for speed-up, while open-system approaches using dissipation might ideally be integrated into quantum chemistry on a fault-tolerant quantum computer to enhance the robustness of quantum algorithms.

C2weakest assumption

That recent proposals for chemically motivated dynamical simulation can be realized on fault-tolerant quantum computers in a way that meaningfully integrates dissipation without introducing new prohibitive overheads (mentioned in the context of fault-tolerant implementation).

C3one line summary

Review arguing that open-system approaches integrating dissipation into quantum chemistry simulations on fault-tolerant computers offer practical advantages for robustness and potential quantum advantage over purely unitary methods.
