摘要
本文讨论了m光子Fock态和压缩真空态构成的迭加态场的量子统计性质,结果表明;这种迭加态中场正交相算符涨落比压缩真空态中的压缩涨落更低,而同时场强比压缩真空态的场强为强.
In this paper the quantum fluctuations exhibiting in the superposition states involving the squeezed vacuum state and the m-photon Fock state are investigated. We show that the squeezed states with stronger intensity and larger squeezing degree compared with initial squeezed vacuum state can be obtained through the squeezed vacuum state.
