We all know of the practical applications like instant communication, computing, teleportation, lag free gaming, etc...
My understanding (admittedly vague) was that you couldn't actually use entanglement to get instant communication, due to the Heisenberg Uncertainty Principle.
So let's say you have two entangled particles, on opposite sides of the world. Each particle can be in one of two states. Before you look at them, they are in a superposition of states.
So let's say Alice measures her particle, to get its state. Bob's particle will then instantly collapse into that same state. But Bob has no way of knowing when this measurement happens, because he can't look at it for fear of collapsing the state of his particle...
All Bob can know is that Alice's particle is in the same state as his particle.
It is spooky action at a distance, but it's not instant communication. That's against the law

Again this is only my understanding of it, which could very well be wrong...
