I just played this online Qubit game that I thought I would put down after a few minutes. Ended up playing for 50 min to finish and actually got a much better sense of how quantum computers work than before. https://quantumai.google/education/thequbitgame

Relatedly, I recently discovered https://algassert.com/quirk — it does require a bit of quantum computing knowledge to use, but the UI is excellent, and I found it incredibly useful for ‘getting a feel’ of how various quantum algorithms work.

This is really fascinating. It would be cool if we had an online group or forum that attempted to brainstorm the simplest/cheapest/(safest?) ways of performing interesting experiments like this that you wouldn’t think you could do at home. I’ve read about a few experiments for determine the speed of light using a microwave that I thought were pretty cool.

https://www.youtube.com/watch?v=ejKCiBZwB34 determine the speed of light using a microwave and marshmallows :)

I'd like to know whether the frequency printed on the microwave was calculated using the speed of light, in which case you'd just be reversing someone else's calculation rather than making an independent measurement of the speed of light.

Here's part 2: https://blogs.scientificamerican.com/critical-opalescence/ho... Simples. So now we can check for ourselves...

Yes, part 2 is key because it's only when he starts measuring polarization that he demonstrates entanglement rather than just the fact that photons are being emitted in pairs.

TIL that there readily available radioactive material/disks sold online…

I have taught a chemistry class where we use those disks. They have a stamp on them that say something like "NRC exempt quantity."

So, apparently, the disks have enough radioactive material to detect, but not enough to cause anyone to worry.
