Quantum pseudo-telepathy is a game that two or more people can play using quantum mechanics. It works like this: two people, who cannot see or hear each other, are given two choices. They don't know what the other person is picking, and they can't talk to each other, but they still need to be able to match their choices. The way they do this is by using quantum entanglement. When two particles (like atoms) get entangled, they become connected in a way that allows information to be sent between them instantly, even if they are very far apart. So the two people can use entangled particles to talk without actually talking! This means that the two people can match their choices, even though they are not talking. It's like a type of mind-reading at a distance.
