Title: Robust Majorana magic gates

Abs:

A universal quantum computer requires a full set of basic quantum gates. With Majorana bound states one can form all necessary quantum gates in a topologically protected way, bar one. In my talk I will start with a discussion of realizations of Majorana states, as well as their potential as an intrinsically protected, topological quantum computing platform. I will then present a protocol that achieves the missing, so called, π/8 'magic' phase gate. The protocol is based on the manipulation of geometric phases in a universal manner, and does not require fine tuning for distinct physical realizations. It is topologically and geometrically protected against all static machine imperfections and low frequency noise.
