Minimal noise in non-quantized gravity

Akira Matsumura, Daniel Carney, Giuseppe Fabiano, Tomohiro Fujita

Non-quantized gravity models must inject a minimum amount of noise to avoid entangling massive objects.

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

for any such model to be non-entangling, a quantifiable, minimal amount of noise must be injected into any experimental system

C2weakest assumption

the non-relativistic limit is Galilean invariant and reproduces the Newtonian interaction on average

C3one line summary

Non-quantized gravity models that preserve Galilean invariance and reproduce Newtonian interaction on average require a minimal noise injection to remain non-entangling.
