Congratulations! The Royal Swedish Academy of Sciences awards the 2025 Nobel Prize in Physics to John Clarke, Michel H. Devoret, and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”
In a series of groundbreaking experiments, the three scientists demonstrated that the mysterious laws of the quantum world can also appear in macroscopic systems—circuits that you can literally hold in your hand. Their superconducting system could shift from one state to another as if passing straight through a wall, and it absorbed and emitted energy only in discrete amounts, exactly as predicted by quantum mechanics.
These discoveries laid the foundation for modern quantum technologies, which are now used in highly sensitive sensors and components found in everyday devices such as smartphones. Without such quantum effects, many of the advanced functions of our phones—like precise navigation and ultra-accurate measurements—would not be possible.
