'Instantaneous travel' is real, but not like in the movies.

Modern science has achieved a form of 'teleportation,' but the mechanisms and capabilities remain very different from what the public commonly imagines.

According to recent studies cited by IFLScience on May 4-5, so-called quantum teleportation allows the transfer of a particle's state from one place to another without moving the particle itself.

This mechanism is based on the phenomenon of quantum entanglement, that is, when two particles are bound together to the point that their states are interdependent regardless of distance.

In a typical experiment, two scientists (often referred to as Alice and Bob) share particles that have become quantum entangled.

Alice performs a special measurement on her particle, causing the state of Bob's particle to change accordingly. However, to complete the "teleportation" process, Alice still has to send information through a normal communication channel. Therefore, there is no instantaneous communication beyond the range of light.

According to Professor Prem Kumar, who works at Northwestern University (USA), the important thing is that quantum teleportation is not the movement of matter, but simply the transmission of quantum information. The initial particle will lose its state while the particle at the other end will precisely recreate that state.

This forms the foundation for future technologies such as the quantum internet and ultra-secure communications.

Experiments have demonstrated the ability to transmit quantum states over distances of more than 1,400km using satellites, showing the potential for global connectivity.

Scientists have even recently successfully experimented with transmitting quantum signals through active fiber optic cables, opening up the possibility of leveraging existing Internet infrastructure.

However, "transporting people" remains beyond the capabilities of current science.

According to the principles of quantum mechanics, it is impossible to completely replicate the state of a complex system like the human body. Furthermore, Heisenberg's uncertainty principle makes it impossible to precisely measure every property of particles.

Scientists estimate that the human body contains approximately 7 x ^10²⁷ atoms. The amount of data needed to fully describe this structure is tens of thousands of times greater than all the data currently available on Earth.

This makes the idea of ​​"transporting people" not only technologically challenging, but also fraught with fundamental physical barriers.

Nevertheless, quantum teleportation remains a significant step forward, promising to change how humans transmit information in the future.
