Universal gates for ising TQFT via time-tilted interferometry

Zusammenfassung:Experiments suggest that the mathematically weakest non-abelian TQFT may be physically the most robust. Such TQFT's-the v=5/2 FQHE state in particular-have discrete braid group representations, so one cannot build a universal quantum computer from these alone. Time tilted interferometry provides an extension of the computational power (to universal) within the context of topological protection. A known set of universal gates has been realized by topologically protected methods using "time-tilted interferometry" as an adjunct to the more familiar method of braiding quasi-particles. The method is "time-tilted interferometry by quasi-particles." The system is its use to construct the gates {g1, g2, g3}.
