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."

Well... we can improve this with sub-atomic particles!

Speaking seriously, it will superb when we could mass manufacture these things. And live enough to see the security hell that this will create too, since almost all your current most popular cryptography algorithms can be broken (at least in theory) by quantum computers.
