By Evelyn Hu It is natural to hold a bias that assumes that the highest-quality devices are those formed from the most perfect materials (crystalline, well-ordered, stoichiometric). Therefore, it is ironic, and perhaps counterintuitive, that particular kinds of defects, such as vacancies (missing atoms) in semiconductor materials, can form the building blocks of a new quantum information tec... » read more
