Topological programmable scalable quantum computing machine utilizing chord line quasi unidimensional aperature tunneling semiconductor structures

A method of fabricating a quantum structure, comprising:

• providing a substrate material;
• fabricating a substantially undoped layer over said substrate material to form a first quantum dot and a second quantum dot;
• fabricating a tunneling path operative to connect said first quantum dot and said second quantum dot;
• fabricating a control gate in proximity of said tunneling path;
• applying a potential to said control gate to control tunneling of a quantum particle through said tunneling path connecting said first quantum dot and said second quantum dot;
• and
• wherein said tunneling path and said control gate are operative to yield a sufficiently narrow aperture chord line resulting in quasi-unidimensional quantum operation.
