Current flowing along the edges of a promising quantum device is insensitive to its magnetic impurities
Conductors of electrical current, including copper, heat up and limit the ability to increase circuit densities. Unusual materials that exhibit the so-called ‘quantum spin Hall effect’, in which ...
