Graphene just unlocked “impossible” quantum currents without magnets
Researchers have achieved a major breakthrough by generating quantum spin currents in graphene—without relying on bulky magnetic fields. By pairing graphene with a magnetic material, they unlocked a powerful quantum effect that allows electrons to carry information through their spins alone. This discovery could spark a new era of faster, more energy-efficient spin-based technologies.
