The 2025 Nobel prizein physics
The 2025 Nobel Prize in Physics was awarded 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". The three formed a team comprising a professor, a postdoctoral researcher, and a graduate student at the time their groundbreaking experiments were performed. In this talk, I will present an overview of the macroscopic quantum tunnelling experiments using Josephson junctions. I will also highlight how an effort to answer a fundamental question in physics ultimately laid the foundation for today’s large-scale quantum processors based on superconducting qubits.
