Scientists conducted a new study with more than 100,000 volunteer gamers in order to show that the quantum entanglement works. This phenomenon was previously studied by Einstein who was undecided about it, calling it “spooky action at a distance,” also dubbed as the Big Bell Test.
However, while confused by it, Einstein didn’t completely disagree with the phenomenon in the field of quantum mechanics, as he proposed a theory that something else was happening behind the scenes that could be the cause of what he called “spooky action.”
Researchers organized a big Bell test and used the help of 100,000 volunteers. They played games via smartphones and other different devices which were supposed to generate random numbers. Such randomness would be able to discover that there are no hidden sets of variables or structures at play.
After that, scientists used the numbers that were generated to conduct several quantum tests in 12 different laboratories, in which they measured entangled particles such as photons. The big Bell test is designed to prove the idea of quantum entanglement. This experiment closes one of the most famous loopholes in the Bell test, which says that the numbers that are used aren’t really impossible to predict.
According to the scientists, getting those numbers at a random pace is quite difficult, which is why the team arranged for so many volunteers.
“People are unpredictable, and when using smartphones even more so,” Andrew White from the University of Queensland in Australia said in a statement. “We asked folk to contribute unpredictable numbers, using smartphones and so on.”
“These random bits then determined how various entangled atoms, photons, and superconductors were measured in the experiments, closing a stubborn loophole in tests of Einstein’s principle of local realism.”
Local realism is the idea that actions don’t have effects in different locations, meaning that what we observe about the universe stays the same even when we are not observing it.
However, Quantum physics doesn’t necessarily have to stick to those rules. According to the results acquired from the many inputs show that quantum physics can explain the Universe around us, without hidden variables being involved.
“Each of the labs carried out a different experiment, to test local realism in different physical systems, and test other concepts related to realism,” one of the researchers, Martin Ringbauer, also from the University of Queensland said.
“We showed that a key property of entanglement in space, so-called monogamy of entanglement, does not hold in the temporal domain.”
This study continues previous work on Bell tests that were conducted earlier this year. Right now, scientists are working on new levels of randomness which will help realize some quantum ideas, which aren’t set by some kind of pattern hidden in the background.
The experiments are just a small part of the bigger picture, according to the researchers. Apparently, we don’t yet know about everything that it takes to understand quantum physics. Nevertheless, it’s an important step forward about the understanding of entanglement and local realism. Their work was published in the journal Nature on May 9.
