  The manipulation of topologically protected field configurations, already
predicted and experimentally observed in non-centrosymmetric magnets, as
skyrmions, merons and antimerons could definitely have potential applications
in logic gate operations as carriers of information. Here, we present and
elaborate a proof of concept on how to construct a three-input non-canonical
majority gate on a kagome ferromagnet lacking inversion symmetry. By taking
advantage of the existence of edge modes in a Kagome magnet, it is possible to
create topological excitations as merons and antimerons at the edge of the
material. Using atomistic spin dynamics simulations, we determine the precise
physical conditions for the creation and annihilation of merons and antimerons
and, in a second stage, we describe the majority gate functionality.
