Proven scares Einstein violation of the reality


Albert Einsteinthe: Scherl /

An international group of scientists proved the violation of local realism in quantum entanglement, by the test of bell inequalities using absolutely random numbers. These numbers were obtained using one hundred thousand people playing in a mobile app. Thus, it refuted the existence of hidden parameters determining the course of the experiment. This was reported in an article published in the journal Nature.

According to bell’s theorem, quantum mechanics and classical mechanics has fundamental differences. If quantum entanglement is due to the presence of some hidden parameters that determine the result of the experiment, they can be identified in a series of experiments. If bell’s inequality is violated, just the Copenhagen interpretation of quantum mechanics, indicating the probabilistic nature of quantum States. In other words, Heisenberg’s uncertainty principle is a property of the microcosm, and not a consequence of the incompleteness of our knowledge about him.

In the experiment, Bella is checked whether the dimension of one of a pair of entangled particles affects the properties of another, no matter how far they may be from each other, or between the particles there is an “agreement” established in the time of the entanglement when the particles are still able to interact directly with each other. In the latter case, the principle of local realism, however, a number of experiments have shown that it is violated when testing most of the hypotheses, suggesting that particles only seem complicated because of imperfections in themselves experiments, including systematic errors of selection.

The authors of the new paper suggest a significant drawback of such experiments: violation of local realism can be shown only in case if the experimenters are truly free to choose how to measure entangled particles, and particles freely respond to these measurements. However, there is the possibility that the use of physical devices in the tests severely restrict this choice, leaving a loophole for hidden parameters.

To overcome these limitations, scientists used truly random numbers is completely unpredictable. To receive them, the experimenters used the Internet audience, consisting of one hundred thousand participants. Volunteers randomly chose a zero or a unit in a gaming mobile app. These data, comprising more than 97 million bits, served as input data for the 13 different tests to test the bell inequalities (with photons, atoms, ensembles of atoms and superconducting devices). It turned out that in all cases the principle of local realism was violated.

Albert Einstein believed that within the Copenhagen interpretation of quantum mechanics violates the realism of the world and physical objects cease to exist objectively. The scientist believed that this is not true, and the probabilistic nature of particles ‘ behavior is actually deterministic. Quantum entanglement he was called “spooky action at a distance”.
