| 摘 要： | 众所周知,当不稳定量子系统被频繁测量时,量子Zeno效应就会发生,此效应在量子信息和量子通信中具有重要意义.然而,以前人们所研究的量子Zeno效应多数是针对二能级系统.可以验证三能级系统里同样存在量子Zeno效应,这将对不同量子系统量子态跃迁的阻止和量子Zeno效应的理解带来帮助,同时,在此基础上拓展到高维系统,也证明此效应的存在.

| Abstract: | As we know,quantum Zeno effect may appear when frequent measurements are performed on an unstable quantum system.This effect is well popular in quantum information and quantum computation.However,most of the previous discussions on quantum Zeno effect were focused on two-level systems.In order to comprehend quantum Zeno effect and prevent the transition in different quantum systems better,we verified the existence of quantum Zeno effect in three-level systems.Furthermore,the existence of quantum Zeno effect... |
