Recently, many new insights of quantum gravity are brought by the program of emergent gravity from quantum information. An idea in this program is that gravity, which is geometrical and smooth, might emerge as low energy excitations from fundamentally entangled qubits (or generally qudits), which are algebraic and discrete. In this talk, I demonstrate that spinfoam models, on one hand, are made fundamentally by entangled qudits, while on the other hand, emerge smooth gravitational fields in a low energy limit. The result suggests the spinfoam model to be a working example of the above idea in the emergent gravity program.
