Boffins pave way for unhackable messages

GROUNDBREAKING research into a phenomenon could in future render communications impossible to hack, experts have said. Scientists at Heriot-Watt University’s Institute of Photonic and Quantum Sciences made the discovery in their study of quantum entanglement. The phenomenon is when two particles, eg light photons, remain connected, even when separated by vast distances. It will allow future communication networks to be unhackable, the researchers said, even if devices are unsafe or in criminal hands.
