Interesting. I can conceive this makes sense, but I am not sure this indicates that we could use Graphene for quantum topological computation. I am not sure you could consider the electron of a layer of graphene to be “squeezed” in 2D, at least in a manner so that you can build a braid and get a topological qubit. (I guess that you are not implying that in graphene the electron themselves are confined in a 2D space?).
