China launches quantum satellite for ‘hack-proof’ communications

China says it has launched ‘the world’s first quantum satellite,’ with the aim of developing a ‘hack-proof’ communication system that could be used for military and commercial purposes. According to one expert interviewed by the BBC, ‘There are millions of applications. Some people say quantum computing could change everything.’ Still, even when the mission succeeds, it will take a long time to reach the full potential, as ‘there is some mind-bending physics to get past first.’
