When we were discussing the index of refraction we saw that an incoming beam of light will make the atoms rediate again.

在讨论折射率时，我们曾看到入射光束使原子再辐射。

The team does this optically - rather than mathematically, which at these data rates would be impossible - by splitting the incoming beam into different paths that arrive at different times.

该研究小组是采用光学的方法，而不是数学方法，——采用数学方法的话是不可能达到这样的速率的。 ——他们把不同时间到达的光分成不同的路径，在检测器上再把他们合并起来。
