Quantum theory may help net security

National-Security-Agency--008Scientists at the Griffith University in Queensland claim quantum physics will help protect data on the internet.
The researchers said that so-called “quantum steering” can be used to improve data security over long distances.
Project leader Professor Geoff Pryde boasts that the method his team are engineering promises “absolutely secure information transfer”.
He said: “Your credit card details or other personal data sent over the internet could be completely isolated from hackers.”
The scientists used special photon quantum states to program a measurement device at each step of sending code.
He said that quantum systems would secure long distance comms by generating random and uncrackable code.
But that would rely on both parties sharing systems.  But his team has invented something called quantum steering, which is used to maintain communication security and removing trust in third party devices.
