We tend to think quantum tunnelling is a subatomic curiosity, but in 1984 and 1985 physicists at UC Berkeley showed that a superconducting electrical circuit big enough to hold in your hand could tunnel from one state to another — a discovery that won the 2025 Nobel Prize in Physics.

A look at the Berkeley superconducting circuit experiments that demonstrated macroscopic quantum tunnelling and energy quantisation, later recognised by the 2025 Nobel Prize in Physics.
