A Testable Quantum Graph Theory of Spacetime: Predictions for Cryogenic Qubits and Colliders

In the previous version, the Hamiltonian was not explicitly derived, which confined the theoretical predictions to highly complex and currently inaccessible experimental regimes. This work reports an explicitly falsifiable (already today) discrete–quantum‐graph model of spacetime and noise in quantum processors. Continuum limits and recovery of field equations (ℓp→0) remain open for future work; our focus is on delivering real, quantitative falsifiability now.
