Universal Topological Quantum Computation from a Superconductor-Abelian Quantum Hall Heterostructure

Topological quantum computing avoids the problem of decoherence by using noise-resistant non-Abelian anyons to carry quantum information. Materials hosting these exotic particles are scarce, however. Scientists now show that Fibonacci anyons---the holy grail for topological quantum computing---can be realized in a heterostructure composed of a simple fractional quantum Hall material and a conventional superconductor.
