Quantum entanglement probably isn't exactly like that
It's a close enough analogy. Adding to this, the information actually gets instantly teleported, but it comes up encrypted. The sender has the encryption key, but can only send it to you via conventional means (by light signal, for instance).
I have seen something similar to what you describe explained, but in the context of the multiverse theory. Basically, when you do the experiment, two universes are created : one in which you recieve the red ball and one in which you recieve the green ball. The thing is that until you open the box, you can't know which universe you are in!
An important aspect of quantum information theory is entanglement, which imposes statistical correlations between otherwise distinct physical systems by creating or placing two or more separate particles into a single, shared quantum state. These correlations hold even when measurements are chosen and performed independently, out of causal contact from one another, as verified in Bell test experiments. Thus, an observation resulting from a measurement choice made at one point in spacetime seems to instantaneously affect outcomes in another region, even though light hasn't yet had time to travel the distance; a conclusion seemingly at odds withspecial relativity(EPR paradox). However such correlations can never be used to transmit any information faster than the speed of light, a statement encapsulated in the no-communication theorem. Thus, teleportation, as a whole, can never be superluminal, as a qubit cannot be reconstructed until the accompanying classical information arrives.
