Claim 15:
16. A device to facilitate formation of a topological qubit, comprising:
a multilayer structure having a bottom, a top that is opposite the bottom, and a side that extends between the bottom and the top of the multilayer structure, where the multilayer structure comprises the following layers, in order the top to the bottom:
a substrate;
a first layer of aluminum antimonide;
a layer of indium arsenide;
a layer of gallium antimonide;
a second layer of aluminum antimonide;
a layer of aluminum oxide; and
a metal gate layer;

and
a layer of aluminum formed on the side of the multilayer structure such that the layer of aluminum is in contact with at least the substrate, the first layer of aluminum antimonide, the layer of indium arsenide, the layer of gallium antimonide, and the second layer of aluminum antimonide, wherein the first portion and the second portion are divided by a gap that extends along the side of the multilayer structure in a direction between the bottom and the top of the multilayer structure.
