China on Tuesday launched the world’s first quantum satellite, which will help it establish “hack-proof” communications between space and the ground, state media said, the latest advance in an ambitious space programme.
“In its two-year mission, QUESS is designed to establish ‘hack-proof’ quantum communications by transmitting uncrackable keys from space to the ground,” it said.
“Quantum communication boasts ultra-high security as a quantum photon can neither be separated nor duplicated,” it added. “It is hence impossible to wiretap, intercept or crack the information transmitted through it.”
As it happens one of our readers around here is a professor of quantum. More than a 0.2 professor of it as well. So as to the actual claim we’ll leave it to him to comment.
But my own suspicion is that the opposite will apply. That quantum will be easier to crack. Not, of course, because I know anything about the subject at all but because that’s the way I think the universe works. Yes, this is ludicrous physics but a spy plot would add in quantum entanglement. And Bond sneaks into the Chinese factory where they make quantums to put into satellites (and, obviously, qubits into chips and so on) and makes their supply of quantums ones entangled with ones at home in Bletchely Park. At which point we can read all their communications and calculations. And, as I think this works, they our so we only use this system to mislead them while communicating ourselves by tattooing the shaved heads of chavs. No one would notice anyway, would they?
Either that or we really do develop truly 100% secure comms and find ourselves interrupted by a bloke sitting on a cloud and shouting through his big beard “Get off the line!”.
