Atomic Steps Create 'Quantum Highway' for Superconductors, Boosting Efficiency

Scientists in Japan have discovered that atomic steps, just one atom high, can guide quantum vortices through superconductors, making them move over 1,000 times more easily in one direction than another. This breakthrough, achieved by researchers at the Research Center for Materials Nanoarchitectonics (MANA), offers unprecedented control over quantum motion and could lead to a new generation of ultra-efficient superconducting electronics.
