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 engineered Lindbladian renders the code space into an attractive steady-state subspace, realized by coupling the storage mode to a rapidly cooled bath through a controlled beam-splitter and spin-dependent displacement interactions.

C2weakest assumption

That the required system-bath couplings (controlled beam-splitter and spin-dependent displacement) can be implemented with sufficient precision and without introducing uncontrolled decoherence or other errors in experimental platforms such as trapped ions.

C3one line summary

A hybrid continuous-variable discrete-variable autonomous quantum error correction protocol stabilizes the code space as an attractive steady state via beam-splitter and spin-dependent displacement couplings to a cooled bath.
