Researchers are constantly developing ways to decrease the size of transistors in order to increase the power and portability of computers, phones, and other electronic devices. As engineers approach the theoretical limits of size in traditional silicon transistors, some have turned their attention to quantum computing. Developments in this area can unlock powerful computing capabilities and expand our understanding of physics. Susan Coppersmith, the Robert E. Fassnacht and Vilas Professor of Physics at the University of Wisconsin, Madison, and a Sigma Xi Distinguished Lecturer, is at the forefront of these developments. She spoke about her research with American Scientist editor-in-chief Fenella Saunders. A video of the full discussion is available here.
