When we use the formula to caculate two-qubit's entanglement,like these:
Why we use complex conjugate of density matrix but not its Complex Conjugate Transpose?

Well that's.. Unexpected. I'm not sure I should ask for details on the matter, so keeping it on a practical level, how does it work now moderation-wise?
Suppose i have an initial state $|A\rangle=\dfrac{1}{2^{3l/2}}\sum_{x=0}^{2^l-1}\sum_{y=0}^{2^l-1}\sum_{z=0}^{2^l-1} |x\rangle^{\otimes l}|y\rangle^{\otimes l}|z\rangle^{\otimes l}|0\rangle^{\otimes l}|0\rangle^{\otimes l}|0\rangle^{\otimes l}$
Now this state is an equal superposition of all st...
