Quantum Cryptography for Video conferencing

Video conferencing gets quantum security - Scientists from Toshiba's Cambridge Research Laboratory unveiled an invention, which is capable of generating 100 quantum 'keys' every second. This is fast enough for every individual frame of video to be protected by its own encryption. "This makes the system highly secure," says Andrew Shields, who leads the Cambridge team. "It would take an enormous computational resource to crack this frame by frame."
