Quantum loop: US unveils blueprint for 'virtually unhackable' internet
by Staff Writers
Washington (AFP) July 24, 2020

US officials and scientists have begun laying the groundwork for a more secure "virtually unhackable" internet based on quantum computing technology.

At a presentation Thursday, Department of Energy (DOE) officials issued a report that lays out a blueprint strategy for the development of a national quantum internet, using laws of quantum mechanics to transmit information more securely than on existing networks.

The agency is working with universities and industry researchers on the engineering for the initiative with the aim of creating a prototype within a decade.

In February, scientists from DOE's Argonne National Laboratory and the University of Chicago created a 52-mile (83-kilometer) "quantum loop" in the Chicago suburbs, establishing one of the longest land-based quantum networks in the nation.

The aim is to create a parallel, more secure network based on quantum "entanglement," or the transmission of sub-atomic particles.

"One of the hallmarks of quantum transmissions is that they are exceedingly difficult to eavesdrop on as information passes between locations," according to the Energy Department statement.

"Scientists plan to use that trait to make virtually unhackable networks."

The department said early adopters could include the banking and health services sectors, adding that there would be applications for national security and aircraft communications.

"Eventually, the use of quantum networking technology in mobile phones could have broad impacts on the lives of individuals around the world," the statement added.

The agency's 17 national laboratories will serve as the backbone of the coming quantum internet, which has initial government funding.

"The foundation of quantum networks rests on our ability to precisely synthesize and manipulate matter at the atomic scale, including the control of single photons," said David Awschalom, a professor at the University of Chicago and senior scientist at Argonne National Laboratory.

Twitter accelerates user growth amid pandemic, unrest
Washington (AFP) July 23, 2020
Twitter showed strong gains in its user base with more people turning to the short-message social network during the pandemic and civil unrest, according to a quarterly update Thursday that offered positive signs despite a big drop in ad revenues. The short-message social network reported a net loss of $1.2 billion in the quarter, most of that coming from setting aside funds for income taxes. Revenue slumped 19 percent from a year ago to $683 million. Despite some modest rebound from the pandemi ... read more
