Claim 8:
9. A quantum computer, comprising:
a multilayer structure comprising:
a substrate;
a first layer of aluminum antimonide that is layered on the substrate;
a layer of indium arsenide that is layered on the first layer of aluminum antimonide, such that the first layer of aluminum antimonide is positioned between the substrate and the layer of indium arsenide;
a layer of gallium antimonide that is layered on the first lay of aluminum antimonide, such that the layer of indium arsenide is positioned between the first layer of aluminum antimonide and the layer of gallium antimonide;
a second layer of aluminum antimonide that is layered on the layer of gallium antimonide, such that the layer of gallium antimonide is positioned between the layer of indium arsenide and the second layer of aluminum antimonide;
a layer of aluminum oxide that is layered on the second layer of aluminum antimonide, such that the second layer of aluminum antimonide is positioned between the layer of gallium antimonide and the layer of aluminum oxide; and
a metal gate layer that is layered on the layer of aluminum oxide, such that the layer of aluminum oxide is positioned between the second layer of aluminum antimonide and the metal gate layer; and

a superconducting layer of aluminum across 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, where the superconducting layer of aluminum includes a first portion and a second portion, the first portion and the second portion are divided by a gap, and further where portions of 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 are exposed in the gap.
