Quantum Fisher information
Okay kiddo, so imagine fish swimming in a lake. But these fish are not normal fish, they are very very very small and they are also invisible.
Scientists who study these fish want to know how fast they swim and in what direction. So they use something called quantum fisher information to measure it.
Now, quantum fisher information is like a special kind of ruler that can measure things that are very small, like these fish. It uses something called quantum mechanics which means it can measure things that are really really tiny.
Now imagine a fish moving very fast, but it's very hard to see because it's so small. This is where quantum fisher information helps, because it can let us see the fish better and also tell us how fast it's swimming and in what direction.
So, to sum up, quantum fisher information is like a magical ruler that helps scientists measure and understand really tiny things like invisible fish swimming in a lake. Pretty cool, huh?
