Rabi frequency

Okay, so imagine you have a toy car that you can make move by pushing it with your hand. The faster you push it, the faster it goes.

Now imagine there is a tiny particle inside the car that you want to make move too. But this particle is so small that you can't just push it with your hand.

Instead, scientists use a special kind of push that they call the "rabi frequency." It's like a tiny vibration that they send into the car that makes the particle inside move too.

The faster the rabi frequency goes, the faster the particle inside the car moves. And just like how you can control how fast you push the toy car, scientists can control how fast they send the rabi frequency so they can make the particle inside do what they want it to do.
