What the
Dutch physicists did involved something called
quantum entanglement, which Einstein once described as "
spooky action at a distance,"¯ a term that pretty much describes what it is. Entangled particles are sort of the
dysfunctional couples of quantum physics. You know that long-distance relationship you had in college that didn't really work out and every time you and your significant other got on the phone or exchanged an e-mail you wound up getting into a fight and feeling a whole lot lousier than you did five minutes before? That's action at a distance.
[...] The point is, the Delft researchers proved the principle
by isolating target entangled electrons inside two supercooled diamonds placed 10 meters -- or
33 ft. -- apart, creating what one of the physicists described as "
miniprisons"¯ for them. They then manipulated their spin rate and determined that
the behavior of one indeed continued to determine the spin of the other,
and vice versa,
even at that distance. Something similar had been achieved before, in 2009, by University of Maryland researchers, but the experiment worked only one out of every 100 million attempts.
This one succeeded 100% of the time. Next, the Dutch plan to expand their work -- literally -- trying to see if the quantum entanglement holds at a distance of 1 kilometer, or .62 mi.
