What Happens to Entangled Particles During Collider Experiments?

Click For Summary

Discussion Overview

The discussion revolves around the effects of collider experiments on entangled particles, specifically questioning what happens to the entanglement when one particle of an entangled pair is involved in a collision. The scope includes theoretical considerations and potential experimental implications.

Discussion Character

  • Exploratory, Debate/contested, Experimental/applied

Main Points Raised

  • One participant proposes that colliding an entangled particle would likely result in the end of entanglement, expressing curiosity about the phenomenon.
  • Another participant questions which property of the particles is entangled, suggesting that most collisions would break entanglement in most properties, and highlights the difficulty in finding a property that survives the acceleration process.
  • A later reply reiterates the question of which property is entangled, specifically mentioning spin as a classical measurable property and inquiring whether such an experiment has been conducted.
  • Another participant doubts the feasibility of accelerating a particle significantly without measuring its spin, asserting that an inelastic collision would certainly break entanglement and questions the value of conducting such an experiment.

Areas of Agreement / Disagreement

Participants express differing views on the nature of entanglement during collisions, with no consensus reached on the effects of such experiments on entangled particles.

Contextual Notes

Participants note the complexity of defining which properties are entangled and the challenges associated with measuring those properties during acceleration and collision processes.

I'm sure this idea has been considered since the invention of the particle accelerator. What would happen to an entangled particle if it's pair was collided in an accelerator? My guess is simply an end to entanglement but I'm too curious not to ask.

Entangled in which property?
Most collisions would break entanglement in most properties. And it is hard to find a property that survives the acceleration process before.

Was just thinking of the most classical measureable - spin. Also was wondering if this experiment was actually ever performed.
 
I doubt that you can accelerate a particle significantly without measuring its spin. An inelastic collision would certainly break entanglement.
What would you learn from the experiment?
