Quantum “Spookiness” Passes Toughest Test Yet

It’s a bad day both for Albert Einstein and for hackers. The most rigorous test of quantum theory ever carried out has confirmed that the ‘spooky action at a distance’ that the German physicist famously hated — in which manipulating one object instantaneously seems to affect another, far away one — is an inherent part of the quantum world.

cheers for that, spooky action’s always interested me

the British are almost certainly already way ahead on this one

my bets are they are already using it in their subs

“This did not work every time. In total, the team managed to generate 245 entangled pairs of electrons over the course of nine days. The team’s measurements exceeded Bell’s bound, once again supporting the standard quantum view. Moreover, the experiment closed both loopholes at once: because the electrons were easy to monitor, the detection loophole was not an issue, and they were separated far enough apart to close the communication loophole, too.”

I give it five years, max, before someone finds another loophole. The first test proving Bell’s inequality was in 1972.

Do you mean subs = Submarines? and if so how?
