  We study topological excitations in two-component nematic superconductors,
with a particular focus on Cu$_x$Bi$_2$Se$_3$ as a candidate material. We find
that the lowest-energy topological excitations are coreless vortices: a bound
state of two spatially separated half-quantum vortices. These objects are
nematic Skyrmions, since they are characterized by an additional topological
charge. The inter-Skyrmion forces are dipolar in this model, i.e. attractive
for certain relative orientations of the Skyrmions, hence forming
multi-Skyrmion bound states.
