摘要

通过求解系统演化的主方程

研究了在高Q值腔中两能级原子的量子演化及其操控

特别是数值计算了在不同的场情况下原子在导入π脉冲后的演化.研究表明

在弱场情况下

作用于第一个原子的π脉冲不仅导致了第一个原子的量子演化的反演

还导致了后续第2个原子可以再现第1个原子的演化规律

从而为实现操控原子演化的规律和量子信息的传递提供了一种有效的方法.另外还提供了一种简单、方便可研判微腔中光子数的方法. 更多还原

Abstract

This paper has studied atomic evolution and manipulation of two-level atoms in a high-Q micro-cavity

and has specially studied atomic evolution after introducing a π pulse for the first atom.It is shown that

the π pulse leads not only to the reverse of atomic evolution

but it also leads to the recurrence of the first atom evolution in the evolution of the second atom.Therefore

this shows an effective way to manipulate the atomic evolution

and quantum information transfer.We have also proposed a ...
