摘要
本文讨论了光场真空态和n光子Fock态迭加态的二阶压缩特性,证明了只有当n=1.2时光场迭加态能够存在二阶压缩特性。首次证明了光场真空态,单光子Fock态和n光子(n>3)Fock态的迭加态存在二阶压缩特性。
In this paper, the two order squeezing character of the superposition states involving vacuum and the n-photon states was studied. We demonstrated that, for n=1, 2, the superposition satates involving the vacuum and n-photon states can exhibit two order squeezing character. For the first time, we demonstrated that, the superposition states involving the vacuum state, the one-photon state and the n-photon states (n>3) can exhibit two order squeezing character.
