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.
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.
