“Geo-economics by contrast is a game that is played by countries that have already ruled out any warfare at all among themselves. Supercomputers kept out by import barriers cannot be forcibly delivered by airborne assault to the banks or universities that might buy them, nor can competition in the world automobile market be pursued by sinking the car ferries of competitors on the high seas. Armed force has thus entirely lost the dominant role it once had in the age of mercantilism — as an ad…

“While they wrestle with the immediate danger posed by hackers today, US government officials are preparing for another, longer-term threat: attackers who are collecting sensitive, encrypted data now in the hope that they’ll be able to unlock it at some point in the future.” - Hackers are stealing data today so quantum computers can crack it in a decade | MIT Technology Review
Two of World’s Biggest Quantum Computers Made in China
Two of World’s Biggest Quantum Computers Made in China : Two of the most powerful quantum computers in the world to date now both come from China, and new experiments with them re-ignite the controversy over what kinds of problems might be quantum computationally solvable that couldn’t begin to be solved by a conventional supercomputer.

‘Quantum secret sharing’ scheme allows 10 parties to communicate securely – Physics World
‘Quantum secret sharing’ scheme allows 10 parties to communicate securely – Physics World : A “quantum secret sharing” scheme that allows 10 parties share information securely – the highest number so far – has been developed and demonstrated by researchers in South Africa. The protocol involves each party performing quantum operations on the photon without measuring its state and the team says it could help increase both the rate at which data is shared on secure quantum networks a…

Every transistor has a unique quantum fingerprint—but can it be used as a form of ID?
Every transistor has a unique quantum fingerprint—but can it be used as a form of ID? : As trap sites are basically tiny defects that are randomly distributed in an uncontrollable way during fabrication, the number, location, and energy levels of trap sites differ for every transistor. As a result, single-electron effects lead to a unique modification in the current-voltage characteristics, effectively giving each transistor a unique “fingerprint.”
Illinois Physics Researchers Awarded DoE Grants to Advance Quantum Information Science
Illinois Physics Researchers Awarded DoE Grants to Advance Quantum Information Science : Physics Professors Bryan Clark and Taylor Hughes of the University of Illinois at Urbana-Champaign have been awarded US Department of Energy (DOE) grants to develop new quantum computing capabilities. The awards are part of a $37-million DOE initiative supporting research that will lay the groundwork for the development of new quantum information systems and that will use current quantum information capabili…
