"oxygen hole pairs with copper hole... proves how localized hole states form and interact within strong electronic correlation regimes, and how these single-hole states transition into electronic precursor molecules and ultimately form bound Cooper pairs as doping levels change... significant breakthrough toward fully resolving the mechanism behind high-temperature superconductivity... lossless power/ quantum hardware"
