Teleportation creates a new reality

In 1931, the American writer Charles Fort was first described the concept of teleportation in one of his novels. Since then, the term coined by the Fort has been actively used in science fiction is gradually becoming not just a literary concept, but also a truly scientific. So, today, quantum teleportation is becoming not fiction, but a real reality.

Teleportation creates a new reality

Teleportation gradually begins to come into our lives. At least, this concept is no surprise

What is teleportation?

As mentioned above, teleportation, the term has come to us from fiction. However, if this process is in the books showed the possibility of moving humans and objects to even the most outrageous distance, the modern quantum physics is able to transfer the quantum state.

To understand what a quantum state, imagine an ordinary computer that stores data in binary bits of "0" and "1". Compared with such a device, a quantum computer is much more perfect invention, since it can store data in two states simultaneously. In addition, all information of a quantum computer can be teleported to any distance that, in fact, made by scientists from Austria and China.

Perhaps in the future teleportation will replace all the main types of transport

To test the ability of a quantum computer to go beyond the binary code, the researchers conducted a special experiment called "Bell Test". In this case, two photons are emitted in different directions simultaneously, and one of the photons becomes a kind of "test" whose parameters are measured and compared with a second photon of light. As practice shows, the first photon transmitted information somehow has mysteriously teleported to the second photon, no matter how far they are from each other.

Do you think that science will be able to teleport once human? Let's try to discuss it in our Telegram-chat.

A shot from the Star Trek series

For the new study, scientists have adapted the classical experiment for teleportation of a three-level state of a photon, which they call "qutrit". The quantum state in this case - is through any of the three optical fibers extends photon. In this case, we must remember that quantum physics allows a single photon to be in any or all three fibers at the same time. The team used multiport beam splitter for guiding photons, and then manipulated using their states auxiliary photons. Carefully controlling the interference patterns of these tiny particles of light, the team was able to successfully teleport quantum information to another photon, although the two photon never interacted physically.

This experiment shows that quantum teleportation may be effected not only in three dimensions, but theoretically any number of opening perspective measurements. In general, this study is a step towards the use of quantum mechanics to electronics to improve. In the near future quantum internet would connect quantum computers together to transfer data extremely fast through quantum teleportation.
