Hardware, Embedded Systems "A group of researchers has fabricated a single-atom transistor by introducing one phosphorous atom into a silicon lattice. Through the use of a scanning tunnelling microscope and hydrogen-resist lithography, Martin Fuechsle et al. placed the phosphorous atom precisely between very thin silicon leads, allowing them to measure its electrical behavior. The results show clearly that we can read both the quantum transitions within the phosphorous atom and its transistor behavior. No smaller solid-state devices are possible, so systems of this type reveal the limit of Moore's law - the prediction about the miniaturization of technology - while pointing toward solid-state quantum computing devices."

Maybe such would be a computer distantly related to its ancient ancestors of Jupiter or matrioshka brains, but going all the way to being composed "from" (~"in") a quark star... I imagine, in such, power efficiency and portability would also have different scope ;)
