[Spotlight] The Mineral That Could Rewire Quantum Computing | KPsphere

Описание: In 2001, three physicists at Los Alamos proved quantum computing with light was theoretically possible — then spent a decade watching it fail in practice. The gates worked 6% of the time. Scaling them meant drowning in compounding failure. What nobody anticipated was that the photon's worst flaw — its tendency to vanish mid-computation — could be mathematically reframed as a feature, not a bug. When a Croatian-born engineer at Harvard started slicing a 190-year-old geological mineral into films thinner than a blood cell, the physics didn't change. The road did.
