Why did macroscopic quantum tunnelling win the 2025 physics Nobel?

The story so far: Quantum mechanics says that particles can sometimes cross barriers they don’t have the energy to climb, like boring through a mountain instead of scaling it first. This process, called tunnelling, is common in nuclear and atomic physics. The 2025 physics Nobel Prize laureates John Clarke, Michel Devoret, and John Martinis showed … Read more
