Abstract
Topological insulators are new states of quantum matter with novel electronic properties. Inside two dimensional magnetic topological insulators, electrical currents are confined at the edge of the sample, and counter propagating directions are spatially separated like automobiles on a highway. Local electrical resistivity is completely eliminated in such topological insulators, and only terminal or contact resistances remain. We show that this principle can be used to construct chiral interconnects on computing devices where the total resistance is independent of the length, thus eliminating a major obstacle of the electronics technology.
