  We show that non-abelian quantum statistics can be studied using certain
topological invariants which are the homology groups of configuration spaces.
In particular, we formulate a general framework for describing quantum
statistics of particles constrained to move in a topological space $X$. The
framework involves a study of isomorphism classes of flat complex vector
bundles over the configuration space of $X$ which can be achieved by
determining its homology groups. We apply this methodology for configuration
spaces of graphs. As a conclusion, we provide families of graphs which are good
candidates for studying simple effective models of anyon dynamics as well as
models of non-abelian anyons on networks that are used in quantum computing.
These conclusions are based on our solution of the so-called universal
presentation problem for homology groups of graph configuration spaces for
certain families of graphs.
