Secure ‘quantum messages’ sent over telecoms network in breakthrough

Researchers harness quantum mechanics to create communications system that can avoid being hacked
Toshiba Europe researchers have used so-called quantum key distribution cryptography to transfer messages over traditional communication systems

Scientists have sent messages encrypted using principles of quantum physics over a 250km German commercial telecommunications network, in a milestone towards next-generation data security.

Toshiba Europe researchers have used so-called quantum key distribution (QKD) cryptography to transfer messages over traditional communication systems in a way that would be safe from hackers.
