Physicists have succeeded in teleporting information not at the quantum level, but at the "usual" level. However, teleporting a person from one point to another in this way will still not work.
Typically, in the scientific world, the term "teleportation" is used to refer to the so-called quantum teleportation. The latter is fundamentally different from the generally accepted idea. In this case, nothing is transferred anywhere in space: we are talking about a kind of copying of the properties of particle A to a similar particle B, which is at some distance.
“Elementary particles, such as electrons and photons, exist, strictly speaking, in a special“ smeared ”state, in which their position in space cannot be accurately determined. Within such a system, we can transfer information from one point in this "smeared" area to another, without wasting time. We call this process quantum teleportation, ”says Alexander Szameit, a researcher representing the University of Jena.
The new technique expands our understanding of teleportation. Now it has become possible to teleport information about certain properties of matter in the world of classical (Newtonian) physics. The scientists used laser beams that were appropriately "tied" to each other. This was done using rotating polarizing plates. Researchers have ensured that the information contained in one of the beams is transmitted to the other. True, the rays themselves must be close to each other.
Scientists say the experiment could change our understanding of teleportation. As it turned out, we are faced with a kind of universal phenomenon that exists not only within the framework of what we call the "quantum microcosm".
However, "teleportation" in the usual sense for us remains the same distant prospect. So, with the help of the new technique, it is impossible to teleport a person from one point to any living or inanimate matter to another point. At the same time, this technique can be useful if you need an instant transfer of information within, for example, computing devices.
In general, science does not deny the hypothetical possibility of "full" teleportation of this or that object, but it makes its own adjustments. It is indicated, for example, that such a phenomenon will rather not be the transfer of an object from one point to another, but rather its copying. As a result, teleportation also poses moral and ethical restrictions.
Earlier, we recall, another group of specialists studied the reaction of the human brain to instantaneous movement from one point to another. For this, special electrodes implanted in the brain were used.
