Quantum entanglement is one of the most intriguing phenomena in physics, but many presentations of the subject leave a false impression that it provides a sort of "remote control" for changing the state of a distant particle by local manipulation of its entangled partner. We discuss a simple example, suitable for undergraduate quantum mechanics classes, showing that this is false, and demonstrating the limits of entanglement.
