Entanglement is the weirdest feature of quantum mechanics. David Mermin (1981) provides an accessible introduction to experiments showing that local determinism doesn’t hold in the quantum world, simplifying Bell’s theorem and tests thereof. This knitted Markdown file shows the sums in R. It’s probably only going to make sense if you have been here before, but hadn’t got around to doing the sums yourself (that was me, before writing this today!).
