# phys: apropos of "Wigner’s Friend" paradox, now tested in a real experiment ...

<< Back in 1961, the Nobel Prize–winning physicist Eugene Wigner outlined a thought experiment that demonstrated one of the lesser-known paradoxes of quantum mechanics. The experiment shows how the strange nature of the universe allows two observers-say, Wigner and Wigner’s friend-to experience different realities. >>

<< Last year, (..) physicists noticed that recent advances in quantum technologies have made it possible to reproduce the Wigner’s Friend test in a real experiment. In other words, it ought to be possible to create different realities and compare them in the lab to find out whether they can be reconciled. >>
