Any theory, no matter how clear and generally accepted it may be, always requires verification. Even if the well-known Albert Einstein was its author. As reported by the editors of the journal Nature, recently an international group of scientists tested the statement of the great scientist about the quantum entanglement of particles. Moreover, thanks to a specially created computer game, Einstein's statement was called into question.
The bottom line is this: there are fundamental differences between quantum and classical mechanics. According to the concepts of classical mechanics, distant objects cannot instantly influence each other. But within the framework of quantum mechanics this is possible, and the properties of quantum particles can be "entangled", that is, interconnected. If the state of one particle in such a system changes, the state of all particles associated with it automatically changes. Even if they are located at a great distance from it. However, Albert Einstein did not agree with this conclusion. Indeed, in this case, the "signal" about a change in the state of a quantum particle can be greater than the speed of light. The famous physicist called this behavior "creepy long-range action", saying that particles have "hidden parameters"which endow them with a certain algorithm for changing properties.
In order to find out where the truth is, the authors of the new work decided to use random numbers, the appearance of which cannot be predicted. A large-scale event The BIG Bell Test was organized. Scientists asked a 100,000 Internet audience to randomly select 0 or 1 in a special gaming mobile application. This data included over 97 million bits. And they were used in 13 different laboratories around the world to test Bell's theorem.
In a simplified form, the essence of Bell's theorem says that an experiment can be carried out with elementary particles, the statistical results of which will confirm or refute the presence of those very "hidden parameters". It turned out that in all cases the principle of local realism was violated and a change in the state of one of the entangled particles really affects the state of the one associated with it. This could mean that quantum physics does not rely on any of the "hidden parameters" and "eerie long-range action" that Albert Einstein spoke about. At the same time, the organizer of the project, Morgan Mitchell, said that this dispute still remains "not fully resolved and partly philosophical."
