八光子相干态是类虚化态

EightPhoton Coherent States are ShadowedLike States

量子辐射场的虚化态［１］是Ｓｒｉｎｉｖａｓａｎ和Ｌｅｅ从一个真实的量子辐射场的物理态和与之对应的非物理态的分布函数出发引入的，而类虚化态［２］是ｄｅＬｉｍａ等人从真实的物理态出发引出的。

Shadowed states were introduced in the literature.Based on the concept of a shadowed state,recently,A.F.de Lima et al have proposed shadowedlike states.In this paper,we show that eightphoton coherent states are shadowedlike states.
