Nonclassical light
Okay kiddo, you know how light from your torch or the sun always looks the same, right? Well, nonclassical light is not like that at all. It is very very different.
Classical light is just like a wave, you know like the waves you see on the beach. But nonclassical light is more like a wave that is not always a wave. It can be a particle or a wave depending on how you look at it.
You remember how you can see a straight stick in the water that looks bent? That is because light waves can bend when they move from air to water. But with nonclassical light, the bending is even weirder. It can actually look like it's in two places at the same time!
Scientists use special tools called "quantum detectors" to study nonclassical light. These detectors help them to see things like "squeezed states" where the light is more stretched in one direction than the other.
Nonclassical light might sound like it's from a different world, but it's actually pretty important. Scientists use it to study all sorts of things like atoms, molecules, and even the tiniest parts of our bodies. So, it's pretty cool stuff!
