Researchers use graphene encapsulation to grow air-stable 2D superconductors for quantum circuits

MIT researchers have developed a new technique called encapsulation epitaxy to grow air-stable, wafer-scale 2D superconductors. By using graphene to shield the material during growth, they have overcome a major hurdle in creating practical quantum computing hardware.
MIT researchers, together with collaborators from Harvard University, Rice University, Yale University, MIT Lincoln Laboratory and Pohang University in South Korea, have developed a technique that uses graphene to grow air-stable, wafer-scale monolayer superconductors, addressing a longstanding barrier to using these ultrathin materials in practical quantum computing hardware.
