How Can a Single Atom Power a Lightbulb?

Imagine you have a tiny, super-powerful robot that can do big things, like lighting up your room. A quantum dot is like this robot. It’s just one atom or a few atoms big, and it can make light so bright it can power a whole lightbulb. Scientists use these little dots in special lights because they're super small and really efficient, kind of like having tiny engines that are more powerful than they look.
