When I was younger and somebody asked me what super power I wanted, I always said “teleportation”. Teleportation could solve many problems in the world. But will we ever be able to move like in science fiction films? So far, the teleportation seems to be heading in a slightly different direction.
The topic of teleportation is extremely interesting, but at the same time very hard to understand, because it is based on quantum physics. Everyone knows what teleportation is, but not everyone knows that the work on its development started a long time ago, because it was in Einstein’s time. But everything happens on the level of micro-scale – that is quantum particles, which behave slightly differently than everything that is visible from the level of macro-scale. In short, as mankind we can “pair” particles at the quantum level with each other. We can transfer the state of the particles from A to B, but we do not transfer the right information. We do not have such technological capabilities to develop a special channel for this purpose, which would carry this information at the speed of light.
PROGRESS ON TELEPORTATION
In its current form, teleportation aims at instantaneous data transfer and to revolutionize computing power. Qubit is the simplest information unit in quantum physics. Nowadays, teleportation consists in the interweaving of these particles, thanks to which information occurring in place A, will also occur in place B. Now the researchers have managed to make this type of teleportation over a distance of 22 kilometres using a quantum computer from Caltech. The recipient was Fermilab’s quantum network. The previous record was 6 kilometres and was set in 2016. This means that we are talking about the foundations of the existence of quantum internet. Of course, this does not mean that in a moment the Internet will change beyond recognition. However, this is a breakthrough that gives rise to further research. Therefore, there are plans to build a much larger scale network around Chicago, called the Illinois Express Quantum Network.
WILL IT EVER BE POSSIBLE TO TELEPORT PEOPLE?
Many people ask themselves this question. Unfortunately, I think that it will never work that way. When we talk about teleportation, we are constantly talking about the transfer of the state of the particle. So this particle must be some kind of “described” state. Meanwhile, the human brain changes every second. There is now ay to stop billiard of synapses or pulses. Perhaps it would be possible to track a person with the information received from the environment, but it will certainly not be the same person with the same brain as at the time of the “transfer”. After all, the state itself is a kind of a record, and in the case of our nervous center, there is not even such a thing as “state”
Of course, no one can predict what the future will bring and it may still surprise us. However, research and technological development is now heading in a slightly different direction.
