The critical temperature of a high-temperature superconductor was systematically tuned using an ionic-liquid gating technique. Measurements of this system revealed a universal quantitative relationship between superconductivity and the strange-metal state, which gives insight into the mechanism responsible for high-temperature superconductivity.
