I'm sorry, but this video did not make anything clear to me. I really liked the visuals but there was absolutely no point in the video that I could find. I feel the narrators could have done a better job explaining what quantum computation IS, rather than going on about superposition. Are these parallel computations going on? What?

Unfortunately, I was lost as well. I have no background in quantum mechanics. I can't help but feel that was needed as a prerequisite to appreciating this video. Sort of like a beautiful analogy. It falls part of you don't understand the concept to begin with.

Unfortunately, that video makes a lot more sense only if you understand quantum mechanics or quantum computation. The video doesn't realy describe what quantum computation is but it rather describes what feature of QM makes quantum computers different from classical computers (superposition and quantum correlations) and why is it so difficult to build or use a quantum computer (decoherence, and the fact that you can't observe or clone the "registers" at intermediate stages in a computation). The video addresses the notion of quantum computing quite obliquely. I would expect this to be the first of a multi-part series where this is explored in more depth (especially given the attention it's receiving).

  It is - well its part 2 of an N-part series. Apparently they are being released as they are being finished, the last one having come about about a month ago. The link is in the text a handful of pixels below the youtube embedding.

    Ah, okay. While skimming, I mistook that to mean that this video on quantum computing was the second in their series exploring diverse topics.

Here's a java simulation I wrote about 10 yrs ago showing visually how a single quit behaves under various operations. Didn't quite get to completing the two quit case (which is where entanglement enters the picture and he's more interesting). https://github.com/jeffwass/Squankum https://github.com/jeffwass/Squankum
