四态叠加多模光场的等幂次N次方H压缩

根据量子力学中的线性叠加原理,构造了由奇、偶相干态光场所组成的一种新型的四态叠加多模叠加态光场|Ψ_o,e⁽⁴⁾Ⅲ〉_q.它是由多模虚奇相干态和多模虚偶相干态这两者的线性叠加所组成的.利用多模压缩态理论详细研究了态|Ψ_o,e⁽⁴⁾Ⅲ〉_q的等幂次N次方H压缩特性.结果发现:当腔模总数q与压缩次数N的乘积为奇数时,若各模初始相位和qj＝1φ_j、态间叠加几率幅γ_o、γ_e以及态间相位差θ_e-θ_o等相关参量满足一定的不同条件时,态|Ψ_o,e⁽⁴⁾Ⅲ〉_q可分别呈现以下非经典效应:i)等幂次N次方H压缩;ii)"半相干态"效应.

Equal-order N-th power H-squeezing of a Four-state Superimposition Multimode Light Field

According to the linear superimposition principle in quantum mechanics, a new kind of four-state superimposition multimode superimposition state light field |Ψ_o,e⁽⁴⁾Ⅲ> q is made up of multimode imaginary odd coherent state and multimode imaginary even coherent state. Based on the multimode squeezed state theory, the properties of equal-order N-th power H-sqeezing of the state |Ψ_o,e⁽⁴⁾Ⅲ> q is studied, and it is found that when qN is an odd number, if the addition of initial phase of each vertical order qj＝1φ_j, the phase difference θ_e-θ_o, the probability amplitude γ_e,γ_o of four-state superimposition and other parameters take different fixed value, the state |Ψ_o,e⁽⁴⁾Ⅲ> q presents the following effect:1)equal-order N-th power H-squeezing;2)"half coherent state" effect.
