      📣 Announcing an experimental new tool for thought 🚨 @michael_nielsen and I have been wondering: what happens if we take powerful ideas from cognitive science and deeply integrate them into explanations? Our first experiment in a new "mnemonic" medium:https://quantum.country/qcvc

      I really enjoyed this -- thanks both of you for making it :) Question -- re CNOT changing its control qubit, you say "It’s honestly not terribly enlightening to follow the algebra through at this point – it’s a lot easier once certain other facts are known to you" 1/2

      Well, you were right, I did the algebra but don't feel enlightened. Now I'm dying to understand. Will this be covered in the next two essays? Or should I look elsewhere? (where?)

      Thanks Joel. No, it won't be (directly) covered. It's one of those things where you accumulate enough other knowledge and it gradually becomes more and more obvious what's going on.

      I can't point to a short, self-contained description which makes it obvious. Someone who'd really mastered chapters 2 & (particularly) 4 of my quantum computing textbook would probably have the tools to see it pretty easily. But that's vastly more effort than it's worth.

      And, to be honest, I'm not 100% sure it's even quite true - it's a long time since I've looked at chapter 4.

          Thanks for the pointers. I think I'll work through the remaining essays as they come out, then maybe move to the book from there :)
