Josephson Radiation from Gapless Andreev Bound States in HgTe-Based Topological Junctions

Abstract

Majorana particles, which are their own antiparticles, offer great potential for future quantum computers, but significant experimental challenges hamper proof of their existence and properties. New measurements of electrical supercurrents in an HgTe quantum well provide a way to gain insight into the induced superconductivity required for these experiments.
