Superconductor Breakthrough Replicated, Twice, in Preliminary Testing

No. At least once lab has actually synthesized the material and verified its superconductivity. It is not just simulations.
A lab in China synthesized a flake of material that behaves the way a superconductor might under a strong magnet, and a separate lab in China made a flake which showed high resistivity. Neither of those qualify for full validation and point to the fact that synthesis has a lot of unknowns that will require more precise doping methods than we have today. This is likely the start of a research path into doped crystals, a path on which a future discovery WILL lead to better conductors that are easy to make.
