Discussion Overview

The discussion revolves around the transformation of Bell states under the influence of a phase gate induced by a magnetic field. Participants explore the implications of applying a phase of Pi/2 to spin-up particles and seek to understand the effects on the triplet Bell state, with references to both theoretical and experimental contexts.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant poses a question about how the four Bell states transform under a phase gate, specifically asking about the triplet Bell state.
  • Another participant requests clarification on the context of the question, suggesting that understanding the motivation might help others provide better responses.
  • Some participants express uncertainty about whether the problem is textbook-related and seek references to assist with the question.
  • A suggestion is made to consider the magnetic field as a quantum logic gate that operates on the state of entangled particles.
  • One participant advises figuring out the evolution operator to address the question posed.

Areas of Agreement / Disagreement

There is no consensus on the nature of the problem, with some participants questioning whether it is a textbook problem while others assert it is not related to homework. Multiple viewpoints exist regarding the approach to understanding the transformation of Bell states under the phase gate.

Contextual Notes

Participants express varying levels of familiarity with the topic, indicating potential gaps in knowledge or references that could aid in understanding the problem. There is also a mention of the relevance of this question to lab experimental work, suggesting practical implications.

Who May Find This Useful

This discussion may be useful for those studying quantum mechanics, particularly in the context of quantum entanglement and phase transformations, as well as for individuals involved in experimental physics related to quantum states.

This is not a homework problem, I hope I am in the right forum.

Suppose a magnetic field is applied long enough so that the spin up particles acquire a phase of Pi/2 expressed as i=squareroot(-1).
How does each of the four bell states transform under this phase gate.
What is exactly happening to the triplet bell state?

Thanks

Can you explain why you need to know this? That might help people to contextualize your question, since it's otherwise a textbook problem.
 
Hello,
If this is a textbook problem, do you know any refrences that can help me solve this. Because I can't find any!
This is a pre-requiste in understanding some lab expermient work.
 
I meant to say this is not due for homework, maybe that is confusing people.
Thanks
Its not a theoretical question.

Sounds like graduate work. Perhaps you should ask your advisor? That what he/she is there for.
 
I will but if anyone can help me asap that much better.
 
Figure out what the evolution operator is and use it to solve your question.
 
I think you can take the magnetic field as a quantum logic gate, which operates on the state of entangled particles and see what the results will be.
