Experts believe the algorithms used to encrypt online messages will be useless in a decade or two, as computers become powerful enough to crack them. An alternative is to tag messages with light particles entangled with each other through the weird properties of quantum physics. However, until now, physicists have succeeded in transmitting entangled particles only about 100km. Over longer distances, light leaches out of the optical fibres used for ground-based telecommunications, which degrades the quantum signal.
