Scientists develop ultrathin superconductors that can help build more compact quantum devices

MIT researchers have developed a way to grow large sheets of an ultrathin superconducting material, called niobium diselenide, that stays stable in air by sandwiching it under a graphene layer. Previously, this material degraded almost instantly when exposed to air, limiting it to tiny lab flakes. The breakthrough could help shrink quantum computing hardware and build more sensitive quantum detectors.
