"thin cuprate crystal superconducting diode... without application of magnetic fields... clean interface between 2 thin layers of cuprate bismuth strontium calcium copper oxide... high-temperature (-288°F) superconductor... then, at -130°F, stacked them at 45° twist, retaining superconductivity at the interface... maximum supercurrent passing without resistance is based on current's polarity, and reversing might be incorporated into quantum bit; topological phases featuring quantum states protected from imperfections"
