| Abstract: | 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. |
