Gamers participated in a study to better understand quantum physics


A new study involving more than 100,000 volunteer gamers demonstrated now that quantum entanglement works. How the gamers participated is explained: they played through smartphones and other devices were designed to generate completely random numbers, a randomness that should prove there’s no hidden set of variables or structure at play.


The numbers generated were then used in a series of quantum tests across 12 different laboratories, measuring entangled particles such as photons in a variety of setups. For the first time this research proved the numbers used aren’t truly unpredictable. By amassing so many random inputs, the results show that quantum physics really can explain the Universe around us, with no hidden variables involved. “We showed that a key property of entanglement in space, so-called monogamy of entanglement, does not hold in the temporal domain,” one of the researchers, Martin Ringbauer, from the University of Queensland, said. The researchers admit that their experiments are a small part of a bigger picture, and we certainly don’t know everything there is to know about quantum physics.  Now three independent European research groups have managed to entangle not just a pair of particles, but separated clouds of thousands of atoms.
