| 摘 要： | 利用多模压缩态理论研究了一种非对称多模叠加态光场|ΨI(ab)〉q的Nj次方H压缩特性.结果发现:当各模压缩幂次数之和为偶数时,态|ΨI(ab)〉q的第一或第二正交分量可分别呈现出周期性变化的Nj次方H压缩效应,进而揭示了压缩简并产生的根源.

| Abstract: | The properties of Nj-th power H-squeezing in the first kind of asymmetrical multimode superposition state light field |ΨI(ab)>q with the superposition of macroscopically distinct two quantum states are studied in detail.It is found that if the sum of squeezed power number Nj of the all model is an even number, under some certain conditions the state |ΨI(ab)>q can display the effects Nj-th power H-squeezing that changes periodically, and post the foundation of producing degenerate squeezing. |

| Keywords: | Multimode superposition state light field N j th power H squeezing N j H minimum uncertainty state Degenerate squeezing |
