Kavli Invited Talk: Transforming Computing with Atomic Precision

Since 1981 we have had the capability to directly observe matter at the atomic level. In the 1990's this same technology was adapted for atomic manipulation, but the technology faced significant limitations in creating practical working devices. Over the past 25 years, together with my team, we have pioneered a comprehensive, reliable and extremely robust process for making devices in silicon with atomic precision. Using this technology we have demonstrated a number of landmark results, including a fully engineering single atom transistor, an integrated circuit manufactured with 0.13nm precision and a growing number of silicon-based quantum processors. In this talk I will describe how we did it, how the technology is being used to manufacture real-world devices, and why this provides an optimal platform for quantum computing. A wide range of issues will be canvased, encompassing the path from the development of a fundamental fabrication technology with discoveries in atom-scale quantum physics and scaling up manufacturing. ultimately I will show how all this is now being brought together to create genuinely useful products.
