This is remarkable, but these kind of things are only possible at extremely low temperatures and in high magnetic fields, for example this was done at 100mK and in a 4T field, so you won't be seeing intel pumping these out any time soon.
I suspect this transistor suffers from the same problem as all other 'miracle' transistors, including carbon nanotube based transistors, that have been announced over the past decade: the gain < 1, which means you can't build anything other than the most simple circuits out of them.
