Many deep-sea animals have such sensitive eyes that they can detect just a single photon in that dark environment.

许多深海动物的眼睛非常敏感，以至于它们在黑暗的环境中只能探测到单个光子。

If even a single photon comes in and interacts with our qubits, you've lost it.

即使有一个光子进入并与我们的量子比特相互作用， 你也失去了它。

They can form an image even when just a single photon hits each photoreceptor per second.

即使每秒只有一个光子撞击每个感光器，它们也可以形成图像。

Every single photon is turned to good use, either for the perfect levels of daylight inside the building, and all the excess photons are converted into power.

每一个光伏板都得到了很好的利用，无论是达到建筑物内的完美日光水平，还是将所有多余的光线都转换为功率。

This is similar to how it is easy for us to see light waves, but very hard for us to detect a single photon.

这类似于我们很容易看到光波，但很难探测到单个光子。
