Quantum Journal Club: Hong-Ou-Mandel Interference between Two Deterministic Collective Excitations in an Atomic Ensemble
内容： We demonstrate deterministic generation of two distinct collective excitations in one atomic ensemble, and we realize the Hong-Ou-Mandel interference between them. Using Rydberg blockade we cre...
