“In our work, we couple a few electrons in the quantum dot to an electrical circuit known as a terahertz split-ring resonator,” explains Kazuyuki Kuroyama, lead author of the study. “The design is simple and suitable for large-scale integration.” “We’re excited because we use structures that are widespread in advanced nanotechnology – and are commonly integrated into semiconductor manufacturing – to help solve a practical quantum information transmission problem,” says Kazuhiko Hirakawa, senior author. “We also look forward to applying our findings to understanding the fundamental physics of light–electron coupled states.”
