- Abstract: We show that quasicrystals exhibit anyonic behavior that can be used for
topological quantum computing. In particular, we study a correspondence between
the fusion Hilbert spaces of the simplest non-abelian anyon, the Fibonacci
anyons, and the tiling spaces of a class of quasicrystals, which includes the
one dimensional Fibonacci chain and the two dimensional Penrose tiling. A
possible encoding on tiling spaces of topological quantum information
processing is also discussed.

In addition to the closed and open spin chains, we consider systems with a fully connected topology, which may be relevant for quantum machine learning approaches.
