@HyperboIeva In this regard quantum information theory is ahead of quantum algorithms since they have some great textbooks like ones by Watrous and Wilde https://t.co/0MoSQgzTd0 https://t.co/ywYdQcDEge and even some more specialized ones like Tomamichel's

@Arrr______ A stronger version of this is, in fact, very common in the quantum information literature: -2log Fidelity <= KL. It follows from properties of Renyi divergences (https://t.co/Mekosgnkyt)
Finally a got around to fix some of the typos in my book, and a wrong lemma! https://t.co/VByJVRoSLi
