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超过十亿晶体管的芯片。但是，很明显，为了推动扩展的最终限制，必要的想法根本不同。由于行业和政府的投资，技术可用于在纳米和原子量表上操纵物质，其精确度令人难以置信，从而使我们能够将分子和原子设备视为传统晶体管的潜在继承者。已经证明，基于双稳定分子和原子纳米结构动态阵列的现场相互作用的计算范式量子点蜂窝自动机（QCA）已证明可以实施通用计算，并有助于大量减少功率耗散，主要减少扩展常规技术的挑战。令人兴奋的最近实验表明，原子尺度上的功能性QCA设备，提供了有力的证据，表明QCA确实可以达到扩展的最终限制。
