Teleportation. Will it be possible in the 21st century?

Will human teleportation become a reality in the 21st century? While this idea seems futuristic, scientists have been researching quantum state teleportation for years. Experiments with photons and entangled particle states demonstrate that quantum manipulation is possible, which could lead to innovations in cryptography and quantum computing. In this article, we will examine the achievements in this field to date, the challenges that remain, and the potential future applications of teleportation.

December 1, 2000. Will it be possible to teleport a human in the 21st century, that is, to send an exact copy of him remotely? To do this, we would first need to understand the quantum states of all the molecules, atoms, and electrons that make up our bodies. And then somehow recreate them elsewhere. A seemingly impossible feat. Or is it?

By the end of the 20th century, physicists were already able to manipulate individual atoms, arranging them into various patterns and structures. The famous IBM inscription, composed of atoms, is proof of this. In 1997, simple teleportation was achieved for the first time – the polarization state of a photon. Experiments with teleporting quantum states of atoms were also successful. This will be useful in the 21st century for encrypting and transmitting secret messages, i.e., quantum cryptography (breaking such codes will be impossible).

Another application will be the quantum computer, a digital machine based on the laws of quantum mechanics. Individual atoms and molecules will act as components, interacting with each other through teleportation. Such computers will be able to rapidly solve today's most complex computational problems.
