Abstract
We employ analytical and numerical approaches to show that unpaired Majorana zero modes can occur in cores of Abrikosov vortices at the interface between a three-dimensional topological insulator, such as , and a twisted bilayer of high- cuprate superconductor, such as . When the twist angle is close to 45° the latter has been predicted to form a fully gapped topological superconductor up to temperatures approaching its native . Majorana zero modes in these structures will persist up to unprecedented high temperatures and, depending on the quality of the interface, may be protected by gaps with larger magnitudes than other candidate systems.

Published 30 March 2022
A new proposal for generating Majorana zero modes—electronic states with potential for quantum computing—would not require sub-Kelvin temperatures.
