Particle antiparticle collide, teleportation?

Click For Summary

Discussion Overview

The discussion revolves around the concepts of particle-antiparticle collisions, annihilation, and the idea of quantum teleportation. Participants explore the relationship between these phenomena, particularly focusing on what happens to energy and quantum states during and after such collisions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that when a particle and antiparticle collide, they annihilate and produce light, but questions the teleportation aspect where a particle-antiparticle pair appears elsewhere in the universe.
  • Another participant clarifies that in quantum teleportation, it is the quantum state that is teleported, not the particles themselves, and that no particles are destroyed in the process.
  • A participant proposes that the energy of the new teleported quantum state could be the original energy of the particle-antiparticle pair minus the energy of the photon produced during annihilation.
  • Some participants argue that only quantum states can be teleported, not energy, and question the relevance of the particle-antiparticle scenario to quantum teleportation.
  • There is a discussion about whether the concept of energy being "teleported" is valid, with some suggesting it is more about the probability of finding energy rather than energy itself being moved.
  • One participant expresses confusion about the relationship between annihilation and teleportation, seeking clarification on the processes involved.
  • A later reply emphasizes that the collision produces photons and that the concept of teleportation is unrelated to the annihilation process, stating that teleportation involves duplicating the state of a photon rather than moving energy.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the relationship between particle-antiparticle collisions and quantum teleportation. Multiple competing views remain, particularly regarding the nature of energy and quantum states in these processes.

Contextual Notes

There are unresolved questions about the assumptions underlying the discussions of energy and quantum states, as well as the definitions of teleportation and annihilation. Some participants express uncertainty about the clarity of existing explanations.

Hi physicists!

When a particle and antiparticle collide, (annihilation) as i understand, it in some cases transform and radiate light, which I can buy. But what happen in the teleportation part, where the particle antiparticle pair accurs in an other part in the universe? Do someone have some concept that can explain this phenomenon?

Thanks in advance guys.

In quantum teleportation, it is a quantum state that is teleported, not a particle. If you do it with massive particles, starting from three particles, you can transfer the state of particle 1 to particle 3 (via entanglement with particle 2). No particle gets destroyed in the process.

Thanks for your answer. So its a matter of quantum teleportation. Can one say that the new "teleported pair/quantum stage" gets the energy of the original paricle-antiparticle pair minus the energy of the photon that gets di-excitated at the location where the collide happen? And it is the rest energy that gets teleportated?

And how do one calculate on it? :)

I didn't say that. I don't see what your scenario with particles/anti-particles has to do with quantum teleportation.

Only quantum states can be teleported, not energy.

Thanks. Did not you say it was a matter of quantum state teleportation? Is it the probability of where I might find the energy that get teleported? And if so, is it not the same thing as say the energy get "teleported"?

Any how, the question was what happen when a particle/anti-particle collide and get teleported.

As i understand it know from your description, the particle-antiparticle collide, a photon can be made. AND the quantum stage of the particle/Antiparticle pair get teleported? I found that very strange since then we create a photon from nothing, therefore my counterquestion was if the teleported particle/antiparticle pair gets have their original energy minus the energy of the photon? Or do I get this whole thing totally wrong in terms of perspective? :)

You do.

Have you read and understood the link that DrClaude posted back in post #2 of this thread?

Yes! In some sense I got the concept of quantum stage teleportation. BUT, if i got it all wrong, what is it that happens during and after the collide, in a briefly summary, and in a complex description? Or is this a thing no one knows and that's why I can't find good information about it and can't even get the Phd. guys at the university to explain it?

The collision between a particle and an antiparticle is completely unrelated to quantum teleportation.

The particles collide and they produce a pair of photons. Now we have a pair of photons just like any pair of entangled photons; that they came from a particle-antiparticle annihilation is pretty much irrelevant.

We can teleport one of these photons if we wish, but as should be clear from the wikipedia article, the word "teleport" is really quite unfortunate. We aren't moving any energy, we aren't moving the photon anywhere, all we're doing is complicated series of steps that eventually makes a photon somewhere else look a lot like our original photon. (More formally, we've duplicated the state of the original photon, but all that means is that any measurement of any property of the new photon will produce the same result that a measurement of the old one would have given).

Ah okey, thanks for your answer! Now I have a clearer picture :)
