This is good, however there really needs to be one of these videos using our best explanation of quantum computers, which is Everettian or "many worlds".

It is really much easier to understand what is going on in a quantum computer, if you understand that you are dealing with many computers in different universes.

It explains WHY a quantum computer can run a function in parallel: because there actually are many classical computers doing the calculation in different universes.

It explains WHY you only get back probabilities of the outcome: because the only way we can "see into" these different universes is through interference effects where the outputs of all the computers interfere with each other..

So all you have to understand is that you are dealing with many classical computers (which is kinda easy to understand) but that you are limited in how you get to communicate with them.

I have wanted to make a video on this for some time ... someday ... sigh.
