Research conducted at Griffith University in Queensland, Australia, may lead to greatly improved security of information transfer over the internet.
In a paper published in the online journal Nature Communications, physicists from Griffith's Centre for Quantum Dynamics demonstrate the potential for "quantum steering" to be used to enhance data security over long distances, discourage hackers and eavesdroppers and resolve issues of trust with communication devices.
"Quantum physics promises the possibility of absolutely secure information transfer, where your credit card details or other personal data sent over the internet could be completely isolated from hackers," says project leader Professor Geoff Pryde.
