Could fiction become reality? Will a time come when we are able to teleport across space or communicate between universes? The lines between science and science fiction are becoming increasingly blurred. When Captain Kirk of Star Trek calls, Beam me up Scotty and when the spies in Philip Pulman's The Amber Spyglass communicate between universes, both are using the phenomenon known as entanglement. Now quantum mechanics promises that some of our wildest dreams may be realized. Experiments show not only that such bizarre effects might be possible but that they could become reality, perhaps even in our lifetimes.
