(contribution withdrawn) Robustness of Topological Operations with Ultracold Atoms — •Leonardo Mazza1, Matteo Rizzi1, Hong-Hao Tu1, Mikhail Lukin2, and J.Ignacio Cirac11Max-Planck-Institut für Quantenoptik, Garching, Germany — 2Harvard University, Cambridge, USA

Since the discovery of the quantum Hall effect, topological states have influenced the research of diverse communities. Among their exotic properties, quasiparticles obeying unconventional statistics, called anyons, are surely one of the most seducing. Their braiding, i.e. controlled exchange of positions, has been proposed as a possible implementation for quantum computation.

Here we discuss the robustness against different sources of noise of information processing and storing of two topological models, the Majorana-Kitaev chain and the p+ip model. We also propose a setup based on fermionic atoms and molecules where both models are realized and anyons can be manipulated.
