A tiny machine: Engineers design an infinitesimal computing device
In 1959 renowned physicist Richard Feynman, in his talk “Plenty of Room at the Bottom,” spoke of a future in which tiny machines could perform huge feats. Like many forward-looking concepts, his molecule and atom-sized world remained for years in the realm of science fiction.
And then, scientists and other creative thinkers began to realize Feynman’s nanotechnological visions.

Imagine Google buying up all these discoveries in the nano and quantum fields. pouring them into their Quantum Computer. Have some kind of super quantum computer evolution like the LHC which gets updated on an ongoing basis
“A nanoscale 8-bit adder operating in 50-by-50-by-50 nanometer dimension”

An “8-bit adder” is serious computing power. Wow. There’s a heck of a lot of difference between a few transistors and an 8-bit adder. Still just theoretical, unfortunately. I look forward to hearing more about this.
Just as I don’t look forward to hearing more about quantum computers. Unless it involves miniaturisation of the Josephson junction.
When I say that an “8-bit adder” is serious computing power, the following is what I mean. It shows the logic diagram for an 8-bit adder.
Compare that with the image in the OP.
Hard to believe that it’s the same logic.
