Two-Photon Dynamics in Coherent Rydberg Atomic Ensemble
Two-Photon Dynamics in Coherent Rydberg Atomic Ensemble
We study the interaction of two photons in a Rydberg atomic ensemble under the condition of electromagnetically induced transparency, combining a semiclassical approach for pulse propagation and a complete quantum treatment for quantum state evolution. We find that the blockade regime is not suitable for implementing photon-photon cross-phase modulation due …
