Quantum entanglement allows you to know something about a far-away system that you couldn't have been told by communication, but you can't control what information is passed. Essentially, you both get a random result, it's just that you both happen to know what result you both got. That doesn't allow you to communicate anything to each other. The best it does is allows you to both get the same random number at the same time. Try constructing an experiment where one side answers a predetermined question, and you'll notice that you can't.
