Almost all people at least once in their life watched sci-fi films, in which the main characters had access to such technologies as an exchange of thoughts, teleportation over long distances, time travel and much more. In reality, all these technologies, unfortunately, still remain only a figment of the human imagination. Or maybe not? Recently, scientists have begun to talk about some of them as about quite achievable things. For example, the exchange of thoughts is quite possible with the help of neurocomputer interfaces, on which several large companies are already working. We talked about this in detail in a separate article and will not focus your attention on this now.
As you have already guessed, in this article, we will talk in detail about another futuristic technology that is partially already available to mankind, so what is teleportation and is it possible to instantly move from point A to point B?
What is teleportation and how is it possible?
A couple of decades ago, the attitude of scientists to teleportation was very skeptical, but with the development of science, the researchers concluded that this is quite possible. Before we start discussing this rather difficult topic, it is important to note that, as of now, humanity is only taking the first steps towards this technology.
Theoretically, there are several methods of teleportation:
- Quantum teleportation is based on quantum entanglement.
- The use of a warp transition involves the use of special drives, with the help of which it is possible to develop superlight speed.
- The theory of “wormhole” is based on the existence of so-called “tunnels” in the Universe, in which space is bent, which allows teleportation over long distances.
Only quantum teleportation shows at least some progress in this direction. What is it like? To understand this, first of all, it is necessary to understand the concept of quantum entanglement. Naturally, within the framework of this article, we will not describe this phenomenon in detail but will tell about it in simple words.
So, this concept appeared from the theoretical assumption, which follows from the fundamental equations of quantum mechanics. Everyone remembers from school, that there are quantum particles in the Universe (electrons, protons, photons, etc.). If they become interdependent, that is, entangled, then their connection is preserved forever, even if to place them at a distance of billions of light years. This means that if two photons are interconnected and one of them is positive, then with a probability of 100%, the second spin will be negative.
We dealt with it, now it is time to talk directly about the quantum teleportation itself. It is the process of transferring that very quantum state (spin) from one entangled particle to another. The spin is destroyed at the point of departure and is restored at the point of reception, while the distance is absolutely unimportant, in theory, the quantum state can be transferred from one edge of the Universe to another.
It is important to understand that quantum teleportation at this stage involves the transfer of particles only, but not energy or substance. Simply put, it does not imply the teleportation of any inanimate objects, not to mention living organisms.
A brief history of quantum teleportation
2009 – the first successful teleportation of a quantum state at a distance of 1 meter was carried out by scientists from the University of Maryland.
2010 – researchers from China made a successful experiment to move the quantum state of a photon over a distance of 16 kilometers.
2015 – USA scientists were able to teleport photons at a distance of 100 kilometers.
2017 – the first teleportation of a photon to near-Earth orbit in the history (distance about 500 kilometers).
Scientists do not exclude that in the future, quantum teleportation will be available not only for particles but also for molecules or even for complex organisms. For example, Professor Hanson, who works at Delft Technical University, believes that:
“If you believe we are nothing more than a collection of atoms strung together in a particular way, then in principle it should be possible to teleport ourselves from one place to another.”
Other teleportation technologies
Recently, many inventors have begun to actively use the term “teleportation” in relation to their developments, although they are not directly related to this phenomenon.
Two years ago, Synthetic Genomics specialists showed their invention to the world: “Biological Teleporter Could Seed Life Through Galaxy”. This device is a converter that is capable to transmit a dataset or even microorganisms over long distances. According to the developers, it is possible to move objects not only to any point of our planet but also to Mars. Synthetic Genomics specialists are confident that if all hospitals are equipped with such converters, it would help to quickly transfer vaccines around the world.
As it was mentioned above, in theory, such a phenomenon as “teleportation” can be achieved by several methods. But at this stage, all key developments in this direction are carried out only with the help of quantum physics. Recall that Albert Einstein was an opponent of quantum entanglement and called it “spooky action at a distance”. Many modern physicists believe that such an epithet to describe quantum entanglement is quite justified. It is important to understand that it works only in the quantum world of elementary particles, which exists by its own laws.
Who knows, perhaps in the future other theories will be proved that will be closely connected with other teleportation methods: such as “wormholes” or superluminal warp drives.
