Here’s an analogy: I put a red card in one envelope, and a blue card in a different envelope. I send one envelope to Alice (but I don’t say which one) and one to Bob. Alice and Bob could be on opposite sides of the planet. When Alice opens her envelope, she knows which colour she has, but she also instantly knows which colour Bob has -- without communication with Bob. Bob might not even have opened his envelope yet. There is no faster than light communication or magic going on.
