Here’s to you, quantum measurement afficionado, who has found their way to the sixth installment, breathless (I hope), to learn of the fate of the famous cat, eponymous with one of the great ones of quantum mechanics. Does she live or die? Can she be both dead and alive? What did this kitten ever do to deserve such an ambiguous fate? And, how many times can you write a blog post teasing cat-revelations and still not talk about it after all? And talk about erasers instead? How many? In my defense, I tried to talk about the cat in this post. I really did. But the quantum eraser, and in particular the double-slit experiment that I have to describe first, took so much room that it was just not in the cards. But rejoice then, this series will be even longer!
