Kohärente Spin-Austausch-Wechselwirkungen ermöglichen eine starke Photonblockade in Kavitäts-EIT-Systemen durch die Abstimmung von Einzel-Photon-Resonanzen mit destruktiver Zwei-Photon-Interferenz, wodurch antibündelnde Emission erreicht wird, während endliche Kavitätspopulati...

Coherent spin-exchange interactions enable strong photon blockade in cavity EIT systems by aligning single-photon resonances with destructive two-photon interference, achieving antibunched emission while maintaining finite cavity populations.

Giant atoms enable simultaneous photon blockades across multiple cavities through multipoint coupling and destructive interference—a capability impossible in conventional point-atom systems. This opens new pathways for quantum light engineering.
