A new part of research suggests that at quantum level there are actually two versions of the same realty. It also touches on the complicated idea that two people can come to different conclusions about the same photos, a particular type of particle, and that both can be accurate in their observations, like Fox News reports. The theory tries to prove that the two observers' statements cannot contradict each other. The study reads: "In quantum mechanics, the objectivity of the objects is not so clear, most dramatically exposed in Eugene Wigner's eponymous thought experiment where two observers may experience fundamentally different realities. -theorems constructed an expanded Wigner's friend scenario with four enthusiasts who allow us to cope with it.
"In a state-of-the-art photon experiment, we here understand the extended Wigner's friend scenario, experimentally break with the associated Bell-type inequality with 5 standard deviations. This result gives great strength to interpretations of quantum theory that are already included in an observer-dependent framework and requirements on the revision of those who are not ".
Referring to two alternative realities, study co-author Martin Ringbauer, Live Science, told "You can verify them both."
However, he added that advances in theory were first required in order to prove Wigner's hypothesis, which was proposed for the first time in 1
Ringbauer added: "Theoretical progress was needed to formulate the problem in a way that is testable. the experimental side, the evolution of the control of the quanta system to implement such. "
The researchers also said that to test the idea that they had" two different laboratories, each involved an experimentator and their friend ".
They used two pairs of entangled photons, admitting that their fate could be intertwined and that people measured a photon in the pair, rec word their results and repeat the process, which wold test the other photos using the quantum memory, where the light is mapped on. atoms and are restored in their original form.
The idea was first introduced by Wigner 1961 and the thesis finally gave the nickname "Wigner & # 39; s friend", but only one scenario was used.
The quantum mechanics work by giving details of how the world works on a scale so small that the rules of physics do not apply.
