MIT team cracks air-stable 2D superconductors for quantum circuits using graphene shield

For decades, the dream of building quantum computers from atomically thin superconductors has been held hostage by a simple, stubborn fact: these materials dissolve into uselessness the moment air touches them. A team spanning MIT, Harvard, Yale, Rice, and institutions in South Korea has now dissolved that barrier instead, devising a method that grows fragile monolayer superconductors already shielded within a graphene embrace. What was once a laboratory curiosity too delicate to scale has become, quietly and precisely, a manufacturable reality.
