摘要
讨论了双模压缩真空态的模间纠缠度与压缩参数的关系,同时指出造成以往文献中双模压缩真空态的模间纠缠度的不同形式的图像产生差异的原因是数值计算的浮点数误差.
The relationship between the inter-mode entanglement degree of two-mode squeezed vacuum states and squeezed parameter was discussed. The viewpoint, that the reason that induced the different figures of the inter-mode entanglement degree of the two-mode squeezed vacuum states in the past reference was the error of float-point number in numeric calculation, was put forward.
