Quantum physics is a young science, which does not prevent the appearance of fantastic hypotheses in it. The perspectives of quantum physics are capable of dazzling any consciousness. Here are just a few examples: the emergence of quantum cryptography, based on the transmission of information by individual photons, and the development of a quantum computer that uses quantum superposition and quantum entanglement to work with information.

An international team of scientists from Austria, Great Britain and France conducted experiments that confirmed the existence of contradictions in the existing theory of quantum mechanics.

Theory of quantum mechanics

Quantum mechanics (wave mechanics) is a theory that establishes a way of describing and the laws of motion of physical systems, for which the quantities characterizing the system and having the dimension of action are comparable to Planck's constant h. This condition is satisfied, as a rule, by the movement of microparticles (electrons in an atom, atoms in molecules, nucleons in nuclei, etc.). However, in some cases, macroscopic systems as a whole possess specific quantum properties. Prove that Vor's quantum postulates contradict classical mechanics and electrodynamics.  The term "quantum" itself has many uses. A quantum of light (electromagnetic field) is a photon. By analogy, particles or quasiparticles corresponding to other fields of interaction are called quanta.

Quantum mechanics is a branch of theoretical physics, a component of quantum theory, describing physical phenomena at the most elementary level - the level of particles.

The effect of such phenomena is comparable in magnitude to the Planck constant, and the classical Newtonian mechanics and electrodynamics turned out to be completely unsuitable for their description. For example, according to the classical theory, an electron rotating at high speed around the nucleus must emit energy and eventually fall onto the nucleus. This, as you know, does not happen. That is why quantum mechanics was invented - the discovered phenomena had to be explained somehow, and it turned out to be exactly the theory within which the explanation was most acceptable, and all experimental data "converged".

Experiment in quantum mechanics

Physicists have long been trying to find contradictions in the theory of quantum mechanics that prevent the observation of quantum entanglement or quantum teleportation in the real world. Many modern scientists believe that there are no boundaries between the quantum world and the macrouniverse, so quantum theory can describe absolutely all processes that take place.

Despite this, in 1967 Hungarian physicist Eugene Wigner discovered the so-called friend paradox with a thought experiment showing the limitations of quantum mechanics.

Scientists conducted laboratory confirmation of Wigner's idea. They used several pairs of observers, one of whom is conducting a quantum experiment, while others are trying to guess its results and results.

We managed to show that in the microcosm of atoms and particles, whose behavior is governed by the laws of quantum mechanics, two observers can simultaneously have different sets of completely verifiable facts. In other words, quantum physics indicates that the phenomena it describes can be subjective.

Experiment participants

As the experiment showed, different pairs of scientists will absolutely always come to opposite conclusions, observing the same process or object of the microworld, if some will analyze what is happening using the principles of modern physics, while others will use quantum mechanics.

During the experiment, scientists used a prototype of a quantum computer, which is now being created by Scottish scientists. In their experiments, they used a pattern: the behavior of these pairs of scientists is described by the well-studied "Bell state" - the simplest form of entanglement, if they measure the properties of entangled particles of light that come from the same source.

In the "Bell state" the particles are always either in coinciding or in opposite states. Moreover, in the context of quantum physics, this experiment showed that, in fact, objective reality cannot exist, since virtual observers showed different measurement results.
