Robust Majorana magic gates
Refael, Gil - California Institute of Technology
Presentation on Thursday, Dec. 3, 2020, noon
Location: Online
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, Pi/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.
