Quantum superposition

Quantum superposition is like a guessing game. Imagine there are two doors, each one labeled with a different letter, A and B. You can't see through the doors, so you don't know what's behind them. In quantum superposition, the doors are both open and closed at the same time! The objects behind each door can be in a mix of two different states at the same time. This means that when you open the doors, you might find a mix of the two different things that could be behind them.
