Can Quentin get Quantum?

May 1st, 2025

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.

“But what is quantum computing? (Grover’s Algorithm)”:

Got Something To Say:

Your email address will not be published. Required fields are marked *

To create code blocks or other preformatted text, indent by four spaces:

    This will be displayed in a monospaced font. The first four 
    spaces will be stripped off, but all other whitespace
    will be preserved.
    
    Markdown is turned off in code blocks:

To create not a block, but an inline code span, use backticks: 

Here is some inline `code`.
