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

we present a protocol utilizing a nonlinear interferometer with linear spectral phases that can generate both high-dimensional spectral qudits and high-dimensional entangled states.

C2weakest assumption

That linear spectral phases can be implemented with sufficient precision and stability to achieve the claimed control over spectral correlations, and that the loss/overlap model accurately captures real experimental conditions.

C3one line summary

A protocol for generating high-dimensional spectral qudits and entangled states via nonlinear interferometry with linear spectral phases, including loss modeling.
