Only consider first qubit. First case: $\frac{1}{\sqrt 3}|0\rangle _1|1\rangle_2 + \sqrt{\frac{2}{3}}|1\rangle_1|0\rangle_2$ $P(|0\rangle_1) = \frac{1}{3}$ and $P(|1\rangle_1) = \frac{2}{3}$ ...

When $H = I_1 \otimes I_2$, $e^{-i\gamma I_1 \otimes I_2} = I_1 \otimes I_2$. Therefore, you don't have to apply any gates. Your CNOT RZ CNOT circuit represents the time evolution of Ising coupling. ...

Can you make a Toffoli-like gate which flips if control bits are equal?

Control bits have the same sign/phase: doesn't flip if $\vert c1\rangle=−\vert c2\rangle$. Flips otherwise. is difficult. If the state is $-\vert 000\rangle$, there's no way to decide $\vert c1\...
