Bell States: Problem & Effects of Phase Gate

[quantumlooser]

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 theoritical 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.
