That would be great, go right ahead, @harshvardhan-pandey !

Correct, the optimal measurements are POVMs (i.e. positive semidefinite operators that sum to the identity). But PSD operators are by definition always Hermitian, so yes, if the operators that form...

To be clear, this is one maximization function that is operating over a choice of $N$ quantum states. The result of this optimization problem should only have one solution (which...

> I see. So it is essentially maximize the maximum of p(rho_k|M_k)? Yes, this is what I take away from it, that's right.

> Interesting. That doesn't seem like a concave objective though. Because even if for each k, p(pho_k|M_k) is a concave function then their maximum is not guaranteed to be. Hmm,...

> From what it looks like based on section 2.5.2, for a given k, we can maximize p(rho_k|M_k) by just tuning M_k and then adjust M_{N+1} at end accordingly. Ah,...

@harshvardhan-pandey No worries! Hmm, I'm not entirely sure how that can be handled either, although I'm definitely interested in hearing about any progress or insights you come up with as...

@harshvardhan-pandey That's true, and that might be worth going down that road. If you do decide to put some cycles on that, feel free to share any of that here,...

Hi @harshvardhan-pandey , From what I can tell, each iteration of the loop is computing the optimal value of discriminating two states (`rho` and `rho_k`) Since these states are orthogonal,...
