Vortex Majorana braiding in a finite time
Thore Posske, Ching-Kai Chiu, Michael Thorwart
Abstract
The authors show finite-time Majorana braiding on the surface of a topological superconductor, by moving a superconducting vortex close to the center of three surrounding vortices. Although the corresponding finite-time quantum gate is not topologically protected in the strict sense, it remains robust against variations in material parameters and in the braiding speed.
