摘要：

Understanding the dynamic evolution of interacting photon pulses in a Rydberg atomic ensemble is a prerequisite for realizing quantum devices with such a system. We present an approach that efficiently simulates the dynamical processes, using a set of local functions we construct to reflect the profiles of narrowband pulses. For two counter-propagating photon pulses, our approach predicts the distinct phenomena, from the widely known Rydberg blockade to the previously less noticed significant absorption in the anomalous dispersion regime, that can occur by respectively setting the pulse frequency to the appropriate values. Our numerical simulations also demonstrate how spatially extending photon pulses become deformed under realistic nonuniform interaction over their distributions. (C) 2016 Optical Society of America
