For example, I like a girl who is very ambiguous with you. At this time, we call her "Schrodinger's sister". Schrodinger's sister has several unknown States, girlfriend, good friend, classmate and stranger. Now she is in the superposition of these States, and you don't know which one she is before the measurement. Only through confession can we know the result, because after confession, the sister is not a superposition state, but the only state among the four States.

Schrodinger's cat is a thought experiment put forward by the famous Austrian physicist Schrodinger, which refers to keeping a cat in a closed container with a small amount of radium and cyanide. Radium has the possibility of decay. If radium decays, it will trigger the mechanism to break the bottle containing cyanide and the cat will die. If radium doesn't decay, the cat will live. According to the theory of quantum mechanics, cats should be in the superposition state of dead cats and live cats because radioactive radium is in the superposition state of decay and non-decay. This dead and alive cat is the so-called "Schrodinger cat". But a cat can't exist both dead and alive, and the result must be found out after unpacking.
