The concrete realization of topological quantum computing using low-dimensional quasiparticles, known as anyons, remains an important challenge. This study proposes quasicrystal materials as a natural platform for topological quantum computing and shows their anyonic behavior. The correspondence between different-dimensional quasicrystals and the fusion Hilbert spaces of the Fibonacci anyons is studied, and a concrete encoding method for topological quantum information processing on quasicrystals is presented.
The concrete realization of topological quantum computing using low-dimensional quasiparticles, known as anyons, remains one of the important challenges of quantum computing. A topological quantum computing platform promises to deliver more robust qubits with additional hardware-level protection against errors that could lead to the desired large-scale quantum computation. We propose quasicrystal materials as such a natural platform and show that they exhibit anyonic behavior that can be used for topological quantum computing. Different from anyons, quasicrystals are already implemented in laboratories. In particular, we study the correspondence between the fusion Hilbert spaces of the simplest non-abelian anyon, the Fibonacci anyons, and the tiling spaces of the one-dimensional Fibonacci chain and the two-dimensional Penrose tiling quasicrystals. A concrete encoding on these tiling spaces of topological quantum information processing is also presented by making use of inflation and deflation of such tiling spaces. While we outline the theoretical basis for such a platform, details on the physical implementation remain open.
