I realised, of course kids can understand quantum... Assume ‖Gender‖²; if a kid asks their mum a question, ans yes/no are equally likely. That's superposition. Once they get the answer, it won't change. That's measurement. If they want a different answer, they ask their dad. That's entanglement.

New incredible detail here: ICE says a match in its facial recognition app Mobile Fortify is a "definitive" determination of a person's status, and that this overrides birth certificates. This is an app ICE is using in the field to scan people

Then to wrap up, @largecardinal.bsky.social and his jolly adventures being a diamond consumer that excites things with many legs in order to create a hackable quantum sensing platform based on diamond nitrogen-vacancy centres.
