真空场注入三态叠加MFSS光场广义电场的等幂偶次Y压缩

The Even-power Y-squeezing of Generalized Electric-field Component of MFSS Light-field with the Three Macroscopically Distinguishable Multimode Quantum Coherent States

对真空场注入三态叠加MFSS(多模泛函叠加态)光场|ψ_0^(3)〉q广义电场分量的等幂次偶次振幅压缩特性进行了详细研究,分析了光场经典强度、经典振幅和经典相位的任意空间分布特征、以及真空场注入对该光场的广义电场分量的等幂偶次Y压缩效应其压缩幅度和压缩量的影响。结果发现:导致态|ψ_0^(3)〉q的广义电场分量存在等幂偶次2m次方Y压缩效应的根本原因在于模间的量子干涉效应、态间的量子干涉效应以及模间和态间的量子纠缠效应;真空场注入可使该光场广义电场分量的2m次方Y压缩效应增强、压缩幅度增大、压缩程度加深。

The multimode squeezed state theory is utilized to study the characteristic of equal-power even-power Y-squeezing of the generalized electric-field component on state |ψ_0^(3)〉q of MFSS(multimode functional superposition state) light-field with the three macroscopically distinguishable multimode quantum coherent states,then the influences of any spatial distributions of the light-field classical intensity,classical amplitude and classical phase,and the injected multimode vacuum field upon both squeezed amplitude and squeezed quantity of equal-power even-power Y-squeezing of the generalized electric-field component mentioned above are analyzed and discussed in detail.It is find that that both the quantum interference effect and the quantum entanglement property of multimode light-field are the innate character that can cause equal-power 2m-th power Y-squeezing of the generalized electric-field component on state |ψ_0^(3)〉q.The injected multimode vacuum field can produce direct influence to the effect of equal-power 2m-power Y-squeezing of the generalized electric-field component of MFSS light-field,and it can causes the squeezed effect of the quantum light field to build up,and squeezed amplitude to increase,and squeezed degree to deepen.
