Good grief. I’m trying to write an essay on Quantum and DNA computing. It’s making my head hurt. So again (with apologies) something silly. Apparently a prison in the South Korean city of Pohang is testing 1.5m robot wardens on inmates. There’s a joke in there somewhere, but my head is too full of superposition and entanglement to function.
BTW, thanks to Matt who spotted this on the BBC News website.
