For the first time, engineers have developed a fast random number generator based on a quantum mechanical process that could deliver the world’s most secure encryption keys in a package tiny enough to use in a mobile device.In The Optical Society's journal for high impact research, Optica, the researchers report on their fully integrated device for random number generation. The new work represents a key advancement... delivering the highest quality numbers and thus the highest level of security — into computers, tablets and mobile phones.
“We’ve managed to put quantum-based technology that has been used in high profile science experiments into a package that might allow it to be used commercially,” said the paper’s first author, Carlos Abellan, a doctoral student at ICFO-The Institute of Photonic Sciences, a member of the Barcelona Institute of Science and Technology, Spain. “This is likely just one example of quantum technologies that will soon be available for use in real commercial products. It is a big step forward as far as integration is concerned.” more
