If you’ve ever questioned the nature of your reality, a new study suggests that there are actually two different versions of it — at least at the quantum level.
The pre-published study, found in arXiv, sheds new light on the complex idea that two people could see the same photon, come to different conclusions about the photon, yet still both be correct.
“In quantum mechanics, the objectivity of observations is not so clear, most dramatically exposed in Eugene Wigner’s eponymous thought experiment where two observers can experience fundamentally different realities,” the researchers wrote in the study. “While observer-independence has long remained inaccessible to empirical investigation, recent no-go-theorems construct an extended Wigner’s friend scenario with four entangled observers that allows us to put it to the test.”
They continued: “In a state-of-the-art photon experiment, we here realize this extended Wigner’s friend scenario, experimentally violating the associated Bell-type inequality by 5 standard deviations. This result lends considerable strength to interpretations of quantum theory already set in an observer-dependent framework and demands for revision of those which are not.”
