Homework Statement



[tex]
\hat{\rho} = \left|\Phi_{AB}\right\rangle\left\langle\Phi{AB}\right|
= \alpha ( |Z+>_A|Z+>_B+|X+>_A|X+>_B)* \alpha ( <Z+|_B <Z+|_A+<X+|_B<X+|_A)

[/tex]

Is |Z+>_A|Z+>_B similiar to |00> ? I'm confused wiht notation

I think you will have to explain what |00> is, and what you mean by "similar". Also, what does |X+> mean? An eigenstate of the x-component of spin?

Ignore the question on |00>.

Yes.

referring to the other post: https://www.physicsforums.com/showthread.php?t=389293

Once I have found the reduxed density matrix

p_a with a basis of {
| 1 |
| 0 | }

and p_b with a basis of{

| -1/4(sqrt2) |
| 1 | }


how do I finish off the problem to find the decomposition?
