Nobel Prize in Physics 2025 (nobelprize.org)

Article summary

The Nobel Prize in Physics 2025 was awarded to John Clarke, Michel H. Devoret, and John M. Martinis for their experiments demonstrating macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit. Their research showed that quantum properties can be observed on a human scale, using a superconducting electrical system that can tunnel from one state to another. This discovery has implications for the understanding of quantum mechanics and its potential applications in fields like quantum computing. The experiments involved creating a macroscopic system that behaves like a single giant particle, exhibiting quantised energy levels and measurable quantum effects.
