Conformal field theory describes the universal behavior of systems near quantum phase transitions, where the notion of scale disappears. These predictions long remained unverified. Now, in a chain of Rydberg atoms, physicists tuned to a critical point and recorded the excitation spectrum, finding ch

The experiment showed: contrary to theories, an impurity in a one-dimensional system moves without resistance. After a quick adjustment, the speed becomes constant, no energy is wasted. A breakthrough for quantum communication.
