【摘要】 目的讨论两个不同多模奇相干态的可分辨性与其内禀参数之间的关系。方法采用两个不同态的密度算符距离函数方法,从理论上研究两个不同多模奇相干态光场之间的距离。结果得到了两个不同多模奇相干态之间的距离函数Do(rj,rj′)。结论结构相同的两个多模奇相干态光场之间不可分辨;模数相同且相互平行的两个多模奇相干态光场具有相似性,只能部分地分辨;模数相同且相互正交的两个多模奇相干态光场在一定条件下完全可分辨。更多还原

【Abstract】 Aim To discuss the dependent relationship between separability and inner parameters of two different multi-mode odd coherent state light fields.Methods The distance between two different multimode odd coherent state light fields was analyzed theoretically by the method of distance functions of density operator.Results The distance functions D_o(r_j,r^′_j′) which is between two different multi-mode odd coherent state light fields is obtained. Conclusion Two different multi-mode odd coherent state light fields with same configuration can′t be separated from each other; Two parallel multi-mode odd coherent state light fields with same modulus can but partly be separated; Two orthogonal multimode odd coherent state light fields with same modulus can be separated completely at certain conditions.更多还原
