Can Quentin get Quantum?

Like many… shall we say… classically-trained computer scientists (i.e. old ones), I have only the vaguest notion of how quantum computing actually works.  My understanding of the various topics can be best pictured as a cloud-like set of probability distributions which doesn’t exhibit any very high peaks!

So I was quite taken with Grant Sanderson’s latest video in his ‘3Blue1Brown’ YouTube channel, which does lovely graphical illustrations of mathematical concepts (each of which tends to get viewing figures measured in millions.) It increased my knowledge considerably of the kind of algorithms one might be able to run on a quantum machine.
