Teleportation: Photon particles today, humans tomorrow?


Teleportation: Photon particles today, humans tomorrow?

Chinese scientists say they have “teletransport” a photon from the ground to a satellite in orbit about 1,400 km (870 miles).

For many, however, teleportation evokes something much more exotic. A world previously confined to science fiction becomes reality?

Well, something like that. But we’re not going to be likely to happen to us in the office or on a beach in the Bahamas at any time. Excuse me.

How does it work?
In other words, teleportation transfers the state of a thing instead of sending the thing itself.

Some physicists give the example of a fax machine – information about marks is sent on a sheet of paper instead of the paper itself. The receiving machine obtains the information and applies it to the raw material in the form of paper that already exists.

This is not telecommuting in the direction of Star Trek – instantly transferring material from one place to another – that’s what you instinctively see.

Instead, it is based on a phenomenon known as a quantum entanglement name.
What the quantum entanglement?
Effectively. The phenomenon occurs when two particles are created at the same time and at the same time and therefore have the same existence.

This entanglement continues even as photons separate. This means that if one photon exchange, the other photon at the other location also changes.

Prof. Sandu Popescu of the University of Bristol, working on quantum entanglement since the 1990s.
“Even then, people thought of Star Trek.

But we’re talking about sending the state of a particle, not the billions of billion particles that make up a person, “he said.

“If you think of a distant planet, you should first exchange one billion pairs of interlaced particles, then you should also send other information, this is not trivial, you should not be excited by it.”

How to teleport a particle?
Back to our two intertwined particles. If a third particle interacts with the first entangled particle, the change that occurs in the entangled particle is reflected in its twin.

So the twin contains information about the third particle and actually takes its existence.
Sounds good, what’s the problem?

It was impossible to create a long-distance link between two interlaced particles, since an interlaced photon can travel 150 km from a fiber channel before being absorbed.

Researchers have long seen the potential of a satellite link, because photons can travel more easily into space, but it was difficult to traverse Earth’s atmosphere – variable climatic conditions can deflect particles.
