This common misunderstanding of Grover's algorithm risks wasting limited resources that should go towards deploying actually urgent post-quantum algorithms.

A terrible photo of a dark edged bee fly (the common one) from this lunchtime. The fly is central, in front of green leaves. The bumble-bee style furry body, with a ginger rump; the dark leading edge to the wings; the amazing long proboscis. An insect with style.
Kate Bradbury, in BBC Wildlife magazine, wrote about the dark-edged bee fly. How the fly is synonymous with April for her. So today I went on a search on Royal Holloway campus. After 5 minutes, there they were!

Slow Puncture I’d use every one of them – each tiny symbol / sign – to ‘light up’ my words … and write eye-catching lines: the comma; the colon; the ellipsis; the slash; the question mark; the hyphen; the en and em dash. In stanzas 1-2, it was all there on show (Was there nothing not used? The short answer: No!) But then I came to an unfortunate juncture: my punctuation, you see, got a slow puncture and those small, helpful marks which let my words breathe and made me understood, all started to leave. Hyphens unhappened semi colons got missed apostrophes went awol in commaless lists. “And what of the question marks Oh yes even those (while my brackets and speech marks forgot how to close When the last comma left there was nowhere to pause my words floated by in one endless clause and no one could tell once the full stops departed where one sentence ended and another one started capitals absconded and meaning left too as the breaks between stanzas bowed then withdrew just like the line breaks then all sense gotblurred thelastthingtogowasthegapsbetweenwordsbrianbilston
