In actual quantum cryptography communication,as the single-photon light source is not available,the strong attenuated laser sources are used in the experiments,but it will cause security loop-hole.
实际的量子密码通信中,由于单光子光源还不能制备,实验上使用强衰减激光源代替,这会引入安全漏洞。

Orion, for example, operates near absolute zero, and previous attempts to build single-photon detectors have suffered similar constraints.
拿Orion来说，要在接近绝对零度下运行，而之前尝试建造单个光子检测器的努力同样受到类似的局限。
The atoms had an effect called electromagnetically induced transparency (EIT), which enabled the scientists to separate the single-photon precursors from the main wave packet.
这些铷原子可以产生一种称为“电磁感应光透明”(EIT)的效应，可以帮助科学家从主波包中分离出单个光子前驱。
But this study is the first to experimentally show that optical precursors exist at the single-photon level, and that they are the fastest part of the single-photon wave packet.
而这次的研究则是第一次用实验证明，在单个光子层次上也存在着光前驱，而且它们也是单个光子的波包中最快的部分。
