  Topological quantum matter exhibits novel transport phenomena driven by
entanglement between internal degrees of freedom, as for instance generated by
spin-orbit coupling effects. Here we report on a direct connection between the
mechanism driving spin relaxation and the intertwined dynamics between spin and
sublattice degrees of freedom in disordered graphene. Beyond having a direct
observable consequence, such intraparticle entanglement is shown to be
resilient to disorder, pointing towards a novel resource for quantum
information processing.
