"15% success rate per attempt (previously not possible) using quantum dot (artificial atom) embedded waveguide acting as mediator separating fast/ slow dynamics suppressing single-photon transitions... sculpts/ correlates incoming photons' frequencies creating qudits... scalable since: entangles photons without needing to filter afterward/ uses existing fiber-optics... unhackable even against future quantum computers... future: move from theory to functional on-chip photonic platform"
