| 摘 要： | 通过数值计算，研究了增加光子双模压缩真空态的N次方H压缩效应。结果表明：对于态，光场存在着N次方H压缩效应，而且对于高次方H压缩，在压缩参数较大时，随着场模上光子增加数的增大，N次方H压缩效应增强。

| Abstract: | The N-th power H-squeezing effects of photon field for the photon-added two-mode squeezed vacuum state a+mb+m|ξ> were numerically studied. It is shown that the photon field can exhibit the N-th power H-squeezing effects (N = 1, 2, 3, 4, 5,…);for higher power H-squeezing (N ≥2) and larger γ (γ is the squeezing parameter), as m increases, the N-th power H-squeezing effects increase. |
