This device could make it possible to manufacture electroluminescent diodes of entangled photon pairs, with rates close to one gigahertz (in other words around on billion Hertz).

此装置可以让人们有可能制造频率接近1千兆赫(10亿赫兹)的纠缠光子对电致发光二极管。

Depending on the polarity of the voltage source, one of the two diodes (d) in parallel is used to reduce noise while the other provides a discharge path.

根据电压源的极性，互相并联的两个二极管(D)中的一个用来减小噪声，而另一个二极管则提供放电通路。

Many engineers see nanotubes as an alternative to silicon, the medium in which transistors, diodes and other semiconductor device structures are usually built today.

很多工程师把纳管看作硅的替代品，当今，晶体管、二极管和其他半导体器件通常都是制作在硅这种介质上。

Although the fibre in question could not conduct electricity, the same technique should work with conductive molecules, which could serve as minute diodes and other circuit components.
