Topologically protected braiding in a single wire using Floquet Majorana modes
Floquet systems offer a versatile toolbox for engineering quantum phases that are not allowed or at least more difficult to obtain in equilibrium systems. A prominent example are time crystals, which spontaneously break discrete time-translation symmetry. Closely related to time crystals are Floquet topological phases, such as those found in the driven Kitaev chain. I will discuss how to perform braiding of non-Abelian degrees of freedom - the elementary operation of topological quantum computation - in such a driven topological superconductor. Unlike the equilibrium case, where braiding can only be performed in two-dimensional systems (or at least 2d networks of 1d systems), braiding here is realized in a strictly one-dimensional system, thus potentially simplifying experimental demonstration.
