Discussion Overview

The discussion revolves around the behavior of entangled particles when accelerated in a particle accelerator and subsequently collide. Participants explore the implications of entanglement on spin cancellation and energy conservation, examining theoretical outcomes and the nature of quantum states.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions the assumption that entangled particles would cancel each other's spin and energy upon collision, suggesting that energies do not cancel.
  • Another participant argues that if two entangled particles have opposite spins, they would theoretically have a total spin of zero, but questions what happens to the energy after the collision.
  • Concerns are raised about the definition of entanglement, with a participant noting that entangled particles do not have definite spins individually, only in combination.
  • There is a discussion about the conservation of quantities such as energy and momentum during the collision, regardless of the entangled state of the particles.
  • Some participants express uncertainty about the implications of entanglement on the particles' behavior post-collision, particularly regarding whether they remain entangled.
  • Clarifications are sought regarding the meaning of "collapse" in the context of particle interactions and energy states.

Areas of Agreement / Disagreement

Participants express differing views on the implications of entanglement for spin and energy conservation, with no consensus reached on the outcomes of the collision or the behavior of the particles involved.

Contextual Notes

Participants highlight potential misunderstandings regarding the nature of quantum spin and energy, as well as the specifics of entangled states. There are unresolved questions about the definitions and implications of terms used in the discussion.

TL;DR
What happens with entangled quants if put inside Particle accelarator and shot at each other?
Due to the energie that is put in when entangling quants my question arises in the outcome. If two quants entangled with each other are accelarated in an particle accelarator and hit each other, they should (as i understand it) cancel each others spin out and therefore cancel the energie they both possess. But here my question comes in place, where does the Energie put in to entangle them go? What would be the theoreticall outcome of shooting two entangled quants at each other regarding new particels, aswell as the energie levels that get free?

Thanks for the answers in advance
greetings a physics enthusiast

Why would they do that?

Even if they did cancel each other's spin, that does not imply that their energies would cancel also. Energies don't cancel.

The Spin that they possess if we have two quants should be exactly 0, so if particle one with an positive spin hits particle two witch has a negative spin and they are in an particle accelarator with high speeds the particles entangled shouldnt stay the same so they would cancel out the spin due to the spins having the exact same enrgetic level and speed of rotation just in the exact opposite direction so that we would have (s-)+(s+)=0. But now my question is what happens with the energie after they both collapse when hitting each other in the accelarator? If i have any mistakes in here im sorry for it, english is not my first tounge and im not used to discussing physics on english so i might translate some things wrong.

It makes no sense to talk about entanglement without specifying which properties are entangled.

But with that said.... after the collision we will end up with the same total energy, linear momentum, angular momentum, charge and other conserved quantities as we had before the collision. Whether the particles are entangled in some way won't change this.

If they are in that particular entangled state, yes. There are other possible entangled states which do not have a total spin of 0.

SchrodingersQuants said:

That's not what the entangled state means. In the entangled state neither particle has a definite spin at all on its own. Only the joint state of both particles together has a definite spin.

SchrodingersQuants said:

Meaning, they should no longer be entangled? Why not?

SchrodingersQuants said:
so they would cancel out the spin
I don't see why.

SchrodingersQuants said:

I'm not sure what you mean by this, but energy is not spin, and even if the total spin is 0 that doesn't mean the total energy is 0.

SchrodingersQuants said:
and speed of rotation just in the exact opposite direction
Quantum spin is not due to "speed of rotation".

SchrodingersQuants said:

What do you mean by "collapse"?

I don't think translation is an issue here. I think your not having a very good understanding of the scenario you are proposing is an issue here. If you have a reference you can give for where you are getting all this from, that would help.
