 Dimensions of an Atomic Size Computer

If we somehow manage to make an atomic size computer, it would mean that the dimension, the linear dimension, is a thousand to ten thousand times smaller than those very tiny chips that we have now. It means that the volume of the computer is 100 billionth or 10^-11 of the present volume, because the volume of the "transistor" is smaller by a factor of 10^-11 than the transistors we make today. The energy requirements for a single switch is also about eleven orders of magnitude smaller than t...
