We mean the immediate movement of anything to any place by teleportation which we know from Star Trek, for example.

The problem I see is mainly that we want to move anything and immediately.

Every highlighted word alludes to the laws of physics — “anything” to quantum physics and “immediately” to the theory of relativity.

First of all, I’ll start with quantum physics — we all know we are made of atoms, so if we want to teleport something/someone, we will have to accurately describe all of its atoms.

And that's the problem — we can describe big things with (almost) arbitrary accuracy but we can never describe small particles (electrons, protons, neutrons) with perfect accuracy in principle.

So we will never have a 100% accurate description of anything and therefore there is a real risk that we will not accurately describe the thing we want to move (we won't know exactly where all the electrons are) and therefore it may be (and given the enormous number of particles I would dare to say that it will definitely be) a completely different teleported image.

That’s pretty impractical and I personally wouldn’t get teleported.

The second problem is with the word immediately — it is not possible to transmit any information faster than light.

Just as a matter of interest — the so-called EPR paradox is related to teleportation, with which Einstein wanted to prove that teleportation is not possible. Although this paradox was eventually disproved, Einstein’s belief that we cannot transmit information faster than light still stands up.

So the fact that we teleport particles today sounds interesting but it has no practical use for us.

Although we are able to teleport photons, I don’t expect anything fundamental to change about the above mentioned problems.

Philosophical questions also arise in connection with teleportation — if we copied someone and transferred information about them to another place (even at the speed of light, which we can do — Wi-Fi, GPS, …), what are we going to do with the original image?
