The first demonstration of high-temperature superconductivity in the surface of a topological insulator -- a promising material for quantum computers -- was reported this week by Lawrence Berkeley National Laboratory (Berkeley Lab).
Topological insulators are a unique class of new materials whose bulk properties are that of an insulator, but whose top layer is conducting. Their advantage for future quantum computers is that they are predicted to support what are called Majorana zero modes, which would make the q-bits stored there nonvolatile.
