Combining materials may support unique superconductivity for quantum computing

A team led by Penn State researchers has demonstrated superconductivity at the interface between the fusion of two magnetic materials, a ferromagnet (Cr-doped (Bi, Sb)2Te) and an antiferromagnet (FeTe). The system has all the components required for unique type of superconductivity called chiral topological superconductivity, which could provide the basis for more robust quantum computing.

UNIVERSITY PARK, Pa. — A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing. The new combination of materials, created by a team led by researchers at Penn State, could also provide a platform to explore physical behaviors similar to those of mysterious, theoretical particles known as chiral Majoranas, which could be another promising component for quantum computing.
