Quantum physics just took a leap from theory to reality! Empa researchers have, for the first time, successfully built a long-theorized one-dimensional alternating Heisenberg model using synthetic nanographenes.

By precisely shaping these tiny carbon structures, they’ve unlocked new ways to manipulate quantum states, confirming century-old predictions. This breakthrough could be a stepping stone toward real-world quantum technologies, from ultra-fast computing to unbreakable encryption.
