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

When the detector is in its ground state, a single graviton is absorbed by the detector while it jumps a single energy level by simultaneously emitting a photon; the reverse process occurs when the detector de-excites.

C2weakest assumption

The interaction between the graviton field and the charged oscillators is treated via a perturbative Hamiltonian whose matrix elements are assumed to produce the stated single-graviton, single-photon transitions without higher-order corrections or decoherence dominating.

C3one line summary

Charged quantum harmonic oscillators in a photon-pumped cavity can absorb a graviton while emitting a photon or emit a graviton while absorbing a photon, offering a simple model for a tabletop graviton detector.
