By building a small superconducting circuit, the 2025 Nobel laureates showed that strange quantum effects like tunnelling and energy jumps can appear in something you can hold in your hand.

Quantum physics has long been associated with the world of the very small, the invisible realm of atoms, electrons, and photons. It describes how particles behave like waves, how they can exist in two states simultaneously, and how they can “tunnel” through barriers they should never be able to cross. But a long-standing mystery has puzzled scientists for decades: do these bizarre effects stop at some scale? Where does the quantum world end, and our familiar world begin?

The 2025 Nobel Prize in Physics was awarded to John
