Quantumograph: A Testable Quantum Graph Theory of Spacetime

We’re pleased to share the revised preprint of our work on a discrete quantum-graph theory of spacetime (the Quantumograph). The Quantumograph is a discrete quantum graph model in which continuum field theories — including general relativity and gauge theories — emerge as effective descriptions at long wavelengths. Importantly, the discrete graph model is presented as the fundamental ontology; continuum theories arise only as approximations in a controlled scaling regime. Initial emulations and numerical checks (see our GitHub repository) qualitatively support the construction; true empirical confirmation will require implementation of the measurement protocol described in the paper, which is feasible on current QPU platforms under the conditions we specify. Key testable elements include predictions for qubit platforms (QPU and annealers), microwave/dielectric signatures, two-boundary (retrocausal) tests of causality, CHSH/Bell observables, and relations tying emergent constants to cosmological scales. Feedback and collaboration welcome.
