So. You're telling me you're building a computer than can compute theoreticals and hypoteticals in infinitesimal or to the trillionth of some accuracy of IF? Is that what this is? Essentially? Searching for God? Its not that complicated, ya'll. There is probably a formula for that, and of course that's the motive, you want the shortcut, but if and when you find it, it will still limit you to 3 dimesions and then you're gonna build on more and program more to get it to compute those millions of billions of divergent possibilities until you get the one with the outcome for a time machine (3.5 dimensions). It's easier than that. But I don't want to take the fun out of this for you. So. Proceed.

OK, I'm already lost at the 'teen' level and I'm 43. She says 'measuring' so that my coin is tail. How does she do that? She said nothing about how they measure things till then, only about probabilities that a penny become head or tails. I don't even understand why she says 'measure' instead of 'calculate'.

If you have a list with like 1 trillion numbers of code and only 1 is going to open the safe, the regular computer would go through the list 1 by 1 while the quantum computer would search the entire list at once.

I dont understand why she has gray hair when her face is that of a 20 year old. What is going on?! I mean if it was natural, fair enough you cant control that, but i cant imagine any woman below the age of 50 that wouldnt dye her hair at the sight of the first gray strand. So if its NOT natural and she dyed it like that as a fashion statement, i must ask, why?

This is great. Now I understand QC - well to a certain extend. @Talia. You are looking for having fault tolerance. I fully understand because this is how we always looked at computing. The perfect 100% accurate result - any time. And I'm sure one day somebody will find the solution. In the meantime you may want to look at applications where this is not so relevant. Imperfection is a form of quality that we all see in nature and in the universe. It is indeed a quality. Only imperfection allows evolution, mutation, and variation. Without imperfection - funny isn't it - we would simply NOT EXIST. Here is how it goes: Think about a structure for an airplane wing that is ultra light, still strong enough that it holds the body of a plane, yet flexible enough that it does not break. Your brain comes up with a few ideas, you let it run through a computer, optimize the structure based on let's say a heat map if issues and the build it. If it's working safely produce it and we are all flying with it - actually for centuries. Guess what - the structure that was picked in the first place is absolutely imperfect, still to heavy but it just works. Let an AI system design it and go through a million iterations, It would come up with a perfect solution. IMPERFECTION however saved us time so we could have airplanes long before we even knew about the existence of AI. Another example: Your own company provided the computer to beat - I believe it was Kasparov - in chess. The software however was imperfect because it could not go through each and every possible move but used the ones with the highest probability to win. AlphaGO did the same with go. Every idea we (humans) create is always imperfect, then we perfect it over time and it will still never be perfect. How about letting the good old silicon based computers do their job and focus on apps that doesn't need that kind of perfection but an overall performance increase unreachable for today's silicon based machines. Instead of computing a three dimensional image and simulating it to move with silicon, take a quantum computer and ignore that few pixels that are lost or even whole frames that do not get perfectly represented. Just a thought.

She has a great teaching nature. I know understand some aspects of quantum computing. It's such an abstract idea but her simple physical demonstrations make sense. Other people I have talked to with super high IQs could not explain it to me. Caveat of having a high IQ, sometimes unrelatable explanations of really not so hard to understand subjects. She is amazing. I'm now intrigued to learn more about quantum physics. The prospects of the future of this subject I hope impacts during my lifetime.
