Many researchers have literally spent decades of hard work trying to figure out how to make valid what the theory tells us about the possibilities of teleportation. To understand this a little better, what is sought is that any human being is capable of travel from one place to another in space at this very moment, something that, at least for now, only science fiction films have been made.
As a detail, in real life it is true that some researchers, as we say after years of hard work, have managed to teleport quantum states of certain particles, although, according to the latest scientific information, it seems that this may change as it is over. to make a discovery that, according to some of the most reputable voices in the industry, seems we are closer to being able to teleport from one place to another, although this will not be neither tomorrow nor in 10 years.
In order to carry out quantum teleportation, it is necessary to know in depth what the entanglement principle is and how it works.
As has been revealed by the scientists themselves in the officially published paper, in order for human beings to be able to master teleportation, the first thing we have to understand is what the strange principle called entanglement is and how it works. As a detail, tell you that this principle is by no means a completely new theory, but rather the first physicist to intuit the existence of this phenomenon was none other than Albert Einstein in 1935.
Specifically, this phenomenon is nothing other than the same one capable of causing two particles to affect each other through space and time. At the time, Albert Einstein found this so strange and improbable that he came to refer to him as a 'ghostly action at a distance'. Strange as it may seem, the truth is that entanglement is a very real phenomenon, as well as the fact that in 2015 a team of physicists from the National Institute of Standards and Technology in the United States managed to demonstrate its existence.
Since then, as you are probably thinking, more and more discoveries have not stopped coming to light, such as the fact that we have managed to measure the states that have multiple particles, we can instantly transmit states between one particle and another that is at hundreds of miles away and we've even managed transfer information from particles found on Earth to their homonyms located on a satellite that was orbiting our planet.
To achieve a massive quantum entanglement these scientists have been working for more than four years
Without a doubt, as you can see, we have advanced a lot, although the truth is that teleportation was still a bit far away. Now, it seems that a new step has been taken in this direction thanks to the work carried out by a group of physicists from the OtaNato National Research Center for Micro and Nanotechnologies located in Sweden, who have just achieved precisely what we have longed to achieve for so long.
Going into a little more detail and attending to the explanations offered by those responsible for this project, apparently and to emulate the behavior of subatomic particles they were manufactured two mechanical micro oscillators of just 15 micrometers in diameter each, a measurement that is similar to the width of a human hair. Each of these oscillators is made up of trillions of atoms, something that, compared to what has been achieved so far, where an electron had been teleported, is, to say the least, massive.
Once the oscillators were ready, they were cooled to a temperature very close to absolute zero in order to form a kind of superconducting circuit between them. As a final point, microwaves were used to make the oscillators resonate by emitting ultrasound. To get this work done, the researchers have been dedicated to developing it for four long years, and the result has been the fact that observe quantum entanglement between the two oscillators. The next step will be to teleport the mechanical vibrations of the oscillators.
