"Quantum teleportation involves moving tiny bits of data from one place to another instantly, through a phenomenon know as quantum entanglement. Entanglement is when two linked particles act like twins, even when they're separated, and means that information can instantly be passed from one to the other without them touching.
Researchers are fascinated by quantum teleportation because it could revolutionise the way we carry and transmit data. But they've struggled until now to find ways in which quantum information stored in light can be used in existing communication systems, which are matter-based, and transferred further than a few kilometres."
