What to know about Air-stable, ultrathin superconductors developed for more scalable quantum devices

Researchers from MIT and other institutions have developed a method to grow air-stable, ultrathin superconducting niobium diselenide by encapsulating it under a layer of graphene. This technique allows for the creation of large-scale, uniform superconducting films that can be integrated into quantum circuits without degrading in ambient air.

What happened

Air-stable, ultrathin superconductors developed for more scalable quantum devices Gaby Clark Scientific Editor Robert Egan Senior Editor Super-thin superconducting materials, which are only one or a few atoms thick, have unique properties scientists can…

Why it matters

But these fragile materials degrade so rapidly in air that they are difficult to study or manufacture.

Common ground

Now, researchers from MIT and elsewhere have discovered and harnessed a method to generate a large, uniform area of ultrathin superconducting material that remains stable in air.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
