【摘要】 利用多模压缩态理论,研究了新构造的第I种偶数模四态叠加多模叠加态光场|Ψ(4)oe,|>2q的等幂次N次方X(差)压缩特性。结果表明,当场模数q与压缩幂次N的乘积qN为偶数且任一模光子数nj小于压缩幂次N时,态|Ψ(4)oe,|>2q的2个正交相位分量可同时呈现程度相同的等幂次N次方X压缩效应;当qN为奇数且nj<N,则在其它必要条件下,态|Ψ(4)oe,|>2q的2个正交相位分量可分别呈现等幂次N次方X压缩效应。更多还原

【Abstract】 The properties of equalpower Nth power X squeezing of the first enen number mode fourstate superimposition multimode superimposition state,which is composed of the linear super positions of the multimode even and odd coherent state that they have as same as even number mode,was studied based on the theory of multimode squeezed states.The results show when the qN(q,cavity mode number) is even number,and the photon numbers nj of any mode is less than N,two quadrature phase components of the state appear as equalorder Nth X squeezing in same time;when qN is odd number,nj<N, and also other necessary conditions the two quadrature phase components of the state present the equal power Nth power Xsqueezing effect.更多还原
