With the help of photons, scientists were able to create a model in which quantum particles can move back in time. As it turned out, while the laws may be violated standard quantum mechanics. Physicists from the University of Queensland in Australia set out to simulate a computer experiment that proves the possibility of time travel at the quantum level, predicted in 1991. They were able to simulate the behavior of a single photon that passes through the wormhole in space-time in the past and engages with itself. This trajectory of a particle called a closed time-like curve - the photon back to the original space-time point, ie, his world line becomes closed. The researchers looked at two scenarios. In the first, the particle passes through the wormhole, returning to the past, and interacts with itself. In the second scenario, the photon, forever a prisoner in a closed time-like curve interacts with other ordinary particle. According to the scientists, their work will make an important contribution to the unification of the two great physical theories, which still had each other little in common: the general theory of relativity (GTR) of Einstein and quantum mechanics. Einstein's theory describes the world of stars and galaxies, whereas quantum mechanics explores mainly the properties of elementary particles, atoms and molecules. Einstein's general relativity allows the possibility of an object traveling back in time, which falls at the same time in a closed time-like curve. However, this possibility can cause a number of paradoxes: a time traveler can, for example, to prevent meet his parents, and this would make it impossible his own birth. In 1991, the first time it has been proposed that the time travel in the quantum world can exclude such paradoxes, since the properties of quantum particles are not precisely defined, according to the principle of an indefinite Heisenberg. In the computer experiment, Australian scientists were first studied the behavior of quantum particles in such a scenario. At the same time it revealed new interesting effects, the occurrence of which is not possible in the standard quantum mechanics. For example, it turned out that is possible to accurately identify the different states of a quantum system, which is quite possible, if we remain within the framework of quantum theory.
