Advancements in silicon technology and the computer design tools have enabled the production of chips that have over a billion transistors. However, it has become clear that fundamentally different ideas are necessary in order to push the ultimate limits of scaling. As a result of the investment by both industry and governments, technology is available for manipulating matter at the nano and atomic scale with incredible precision allowing us to consider molecular and atomic devices as potential successors to the conventional transistor. Quantum-dot cellular automata (QCA), a computing paradigm based on the field interaction of dynamic arrays of bi-stable molecular and atomic nanostructures has been shown to implement general purpose computing, as well as contribute to significant reductions in power dissipation, a major challenge with scaling conventional technology. Exciting recent experiments demonstrated a functional QCA device at the atomic scale, providing strong evidence that QCA can indeed reach the ultimate limits of scaling.

硅技术和计算机设计工具的进步使生产具有超过10亿个晶体管的芯片成为可能。然而，很明显，为了推动扩展的最终极限，必须有根本不同的想法。由于工业和政府的投资，技术可以在纳米和原子尺度上以令人难以置信的精度操纵物质，使我们能够将分子和原子器件视为传统晶体管的潜在继任者。量子点元胞自动机（QCA），一种基于双稳态分子和原子纳米结构的动态阵列的场相互作用的计算范例，已被证明可以实现通用计算，并有助于显著降低功耗，这是缩放传统技术的主要挑战。令人兴奋的最近的实验证明了一个功能QCA设备在原子尺度上，提供了强有力的证据，QCA确实可以达到缩放的极限。
