In a composite quantum hypothesis testing scenario with dephasing, the reverse sandwiched Renyi divergence for alpha in (0,1) exactly determines the single-copy Hoeffding exponent.
For composite quantum hypothesis testing with a mixed IID null hypothesis, the optimal type-II error exponent is the worst-case component when type-I error vanishes, but not for fixed nonzero type-I error.
The generalized quantum Stein's lemma remains valid for almost-iid states via a new continuity bound on relative entropy of entanglement with respect to quantum Wasserstein distance.
