Query: Quantum walk on a spin network   We apply a discrete quantum walk from a quantum particle on a discrete
quantum spacetime from loop quantum gravity and show that the related
Entanglement Entropy can drive a entropic force. We apply this concepts to
propose a model of a walker position topologically encoded on a spin network.
