A new study found that Weyl semimetals, a class of quantum materials, have bulk quantum states whose electrical properties can be controlled using light. Insights from quantum physics have allowed engineers to incorporate components used in circuit boards, optical fibers, and control systems in new applications ranging from smartphones to advanced microprocessors...
