Okay, so imagine you have a bunch of friends and you all want to make a really cool sandcastle. But, you don't want to just throw sand around randomly, you want to work together to make something amazing. That's kind of like what coherent control is.
Coherent control is when scientists use lasers to control the way that molecules or even atoms work together. Laser beams are like a really special tool that scientists can use to make molecules do things that they wouldn't normally do.
It's like if you have a bunch of different colored ribbons and you want to make a cool pattern with them. You could just throw them all over the place and hope they make a cool pattern, or you could use your hands to move them around and get them to make the pattern you want. The lasers in coherent control are like your hands moving the ribbons.
Scientists use coherent control to do all kinds of cool things, like create electricity with light, make really fast computers, and even create new materials that we can use to make things like stronger buildings or faster airplanes!
So, basically, coherent control is when scientists use lasers to work together with molecules to make really cool things happen!
