CHINA has scored a victory against hackers and spooks as it surges ahead of other world powers in a new kind of space race.
IN A bid to build an entirely new kind of internet — completely secure and impervious to hackers — China has pulled off a major feat in particle physics.
Chinese scientists have set a new distance record for beaming a pair of entangled particles: photons of light that behave like twins and experience the exact same things simultaneously, even though they’re separated by great distances.
The principle is called quantum entanglement and it’s one of the subatomic world’s weirdest phenomena. And China has smashed the distance record for quantum entanglement.
