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 central result is a simulated set of 90 doubly resonant signal/idler frequency-mode pairs with an effective Schmidt number of 89.62, average bandwidths of 1.08 GHz, a mean free spectral range of 51.9 GHz, and a total internal pair-generation-rate efficiency of 1.16 GHz/mW.

C2weakest assumption

That the classical electromagnetic simulations and the extended quantization formalism accurately capture real-device quantum behavior without unmodeled losses, fabrication imperfections, or deviations from the assumed nonlinear cavity parameters.

C3one line summary

A simulated racetrack resonator design yields 90 doubly resonant frequency-mode pairs for SPDC with 1.08 GHz average bandwidth, 51.9 GHz mean FSR, and 1.16 GHz/mW pair generation efficiency.
