1 - Here follows a GHZ ((|100>+|010>+|001>)/&radic 3) type of situation.
There are 3 people, André, Béatrice and Claude. One of them is guilty. The judge starts questionning each of them. After two hours of cooking Claude, he knows whether he is guilty or not. If he is guilty (|1>) then the other ones are innocent (|00>), however if he is not guilty, the judge has to cook André or Béatrice who are still entangled ((|01>+|10>)/&radic 2).
2 - Now is a W ((|000>+|111>)/&radic 2) type of situation.
André, Béatrice and Claude love each other. When one of them is happy (|1>), the other ones as well (|11>). However when one of them is sad (|0>), the other ones share his sorrow (|00>).
As long as no one expresses any emotion, they don't know if they have to be happy or sad, so they remain entangled ((|000>+|111>)/&radic 2).
