与光场依赖强度耦合多光子通道中原子周期量子回声的产生和控制
Preparation and control for atom periodic quantum echo via light field intensity-dependent coupling multiphoton channel
摘要
Abstract
In this paper, the evolution of the fidelity of atomic states is investigated via a light field intensity-dependent coupling multiphoton channel, the preparation and the control for atom periodic quantum echo is discussed, as well. Considering the effects on the evolution of the fidelity of the atomic states by atomic coherent distribution angle, average photon number of the field, and photon number k absorbed (emitted) as the atom transition, respectively, we obtain the system parameter of preparation and control the atom periodic quantum echo, show up its physical characters of a high-fidelity output of the a-tomic information.关键词
