Majorana zero modes (MZMs) are collective electronic states that could potentially enable error-reduced quantum computing. Usually, these states require extremely cold conditions—not much above absolute zero. A new theoretical proposal imagines MZMs forming at a “balmy” 90 K [1]. The scheme relies on twisted bilayers of a high-temperature superconductor placed on top of a topological insulator. The predicted MZMs would inhabit superconducting vortices on the surface of the insulator.
