1·If we fire the individual photons and have detectors at the slit to find out which way each photon went the interference pattern disappears.
如果我们在放射单光子的时候有检测器在缝的旁边，就会发现每一颗光子的去向，相互干扰就会消失。
2·But her equipment, too, must be set to one mode or the other, and she cannot be certain that the polarity of the photon she sends to Bob is correct.
同样，她的设备也只能选取一种模式进行发送，由于信息是后验的，她并不能确定其送给“鲍勃”的光子极性是否正确。
3·This extension of the photoelectric effect, in which one photon knocks one electron off the edge of an atom, could make physicists reconsider when light is a wave and when it's a particle.
在这种光电效应的延伸中，一个光子从原子的边缘打出一个电子，这可能要使物理学家们重新考虑光在什么情况下是波，什么情况下是粒子。
4·Once entangled, a photon can carry any information stored in the atom's quantum state to other parts of the computer.
一旦发生纠缠，光子可以将储存在原子量子态中的任何信息传递到计算机的其他位置。
5·Du, however, believed Einstein was right and determined to end the debate by measuring the ultimate speed of a single photon, which had not been done before.
然而，杜胜望相信爱因斯坦是正确的，他决心测量单个光子的极限速度，通过这一前无古人的实验来结束这场争论。
1·Compared to the complexity with which our conventional computers and networks function, the ability to store and retrieve a single photon might seem rudimentary.
和我们传统的电脑及网络功能的复杂性相比，这种存储和再现单个光量子的能力看上去还相当简陋。
2·The total photosynthetic photon flux density above and below canopy has a significant diurnal and seasonal changes and the changes of the upper and lower canopy are consistent.
冠层上方和下方总的光合光量子通量密度具有明显的日变化和季节变化，并且冠层上下变化规律一致。
