UNITED STATES (VOP TODAY NEWS) — Researchers say they have demonstrated the possibility of having two facts at one time for a given event, at least when it comes to the quantitative world.
To investigate their hypotheses, researchers at the experimental physics department at the University of Innsbruck in Austria have treated one of the world’s most thought-provoking experiments, the so-called Friend Wiegner.
The experiment, named after Nobel Prize-winning physicist Eugene Wigner in 1961, includes two people watching the same body – in this case, one photon.
When the photon observation process is performed, it is displayed horizontally or vertically, but according to quantum mechanics, before this observation, it is in the case of “overlapping” means that in both cases simultaneously: horizontal and vertical.
In Wiegner’s experiment, someone in the lab monitors the photon, sending it either vertically or horizontally, while Wiegner, outside the laboratory, performs a simple test called the “interference experiment” to prove that the photon is still in a superposition state.
In the experience of thinking, it is possible to prove that the two observations, and thus all the facts that represent them, are true at the same time.
While Wiedner’s friend was an interesting intellectual experience, progress in quantum mechanics and physics allowed researchers to develop theory in the field of study, and this is exactly what Massimiliano Bruitti of Heriot-Watt University in Edinburgh did.
Using six interconnected photons (light particles linked to each other), Bruetti and his colleagues replicated the results of the Wiegner Friend experiment.
When observed, the photons were in a state of polarization, but when tested using interference experiments, the researchers concluded that the photons were still in a superposition state.
It should be noted that the implications of the study not only confirm the experience, which has been discussed for a long time, but mainly challenges how to make observations.
“The scientific method depends on the facts that were created through repeated and universally agreed measurements, regardless of who observed them,” says Broitti in the paper, published in AirXiv, “In quantum mechanics, the objectivity of observations is not very clear.”
