Let’s start with the most famous thought experiment- The Schrödinger’s cat as an example. In this though experiment, a cat is kept in a closed chamber in which there is a glass bottle with a poisonous acid. Connected to a Geiger counter (detector-detects radioactivity), there is a hammer. A radioactive source is also kept inside the box. When the detector detects the radioactivity from the material, the glass bottle is shattered, releasing the poisonous acid and the cat is dead. As an observer we are not aware of the outcome of the experiment. Only if the chamber is opened, the outcome is revealed. So, we can say the cat is live and dead at the same time i.e., in a superposition state.
