"chromium oxide... its electrical properties can morph between high-conductance metallic behavior and low-conductance insulating behavior, depending on its electron configuration... which allow their conductance to be fine-tuned... we can make new devices out of very small amounts of material... In addition... chromium oxide-based spintronics may help pave the way for quantum computing"
